tests_ruby::vertical_ruby_is_upright_to_the_right_of_the_column
checked that no reading glyph is more than 1 pt wider than tall. With
craft-fonts in the build, the kana come from Shippori Mincho, whose か
is 8.24 pt wide and 7.22 pt tall at 10 pt. The test failed on that
glyph although it stands upright. FreeBSD CI, which builds with
craft-fonts at a71c20e3, fails it on every branch since 14f804cd. It
also fails on Windows with that ref or an older craft-fonts checkout.
The test now compares each reading glyph's ink with its own outline at
10 pt. The same width and height mean the glyph is upright; a swapped
width and height mean it lies on its side. It also requires one
reading glyph whose outline is not square.
Its glyphs were put in visual order and then cut where the path ran out, which kept the text's end. Now the longest start of the text, in reading order, whose glyphs fit in visual order is laid out, as area type does with each line it breaks, by the same rules that place the line: steps where the glyphs sit, hanging punctuation and the path beyond the brackets.
Rows two PRs of the batch both changed came out twice in localization-parity, target-app-parity and type-parity; the newest of each is kept. prefs_dialog.rs is formatted.
Illustrator links type in an area or along a path (https://helpx.adobe.com/illustrator/using/manage-text-area.html); until now only area type threaded here. Type on a path that overflows ends its line where its text stops fitting, so a story flows on from it, and its red out port, just past its end bracket, loads the Selection tool with the text as area type's does. A new frame threaded from it at a point is type on a path of its shape.
Optical Margin Alignment and Roman Hanging Punctuation left every
right-to-left paragraph of point and area type, and type on a path
whose first paragraph runs right to left, as it was: the quotation
marks, full stops and commas at the ends of its lines stayed inside
the margins.
A right-to-left line now hangs at the margins its alignment places it
against, as a left-to-right line does. Auto aligns a right-to-left
line at its right, so it hangs there. The line is read from right to
left: where it hangs at its left margin, a full stop and the quotation
mark after it that end the line hang together. In vertical type,
where the characters of a right-to-left paragraph run from the top
down, the pair is read from the top.
Type on a path whose first paragraph runs right to left hangs at its
brackets by the same rule. In horizontal type, Auto places it at the
end bracket, so it hangs there. On a closed path, its hang at the end
bracket gets the space between the end and start brackets before its
hang at the start bracket does, as in right-aligned type.
A justified right-to-left line of one word is spread between its
letters as they are drawn. The gap after each letter went to the
letter that follows it in the text, so the two leftmost letters
touched and the word ended one gap short of the right margin.

a_zero_width_joiner_in_devanagari_asks_for_a_half_form took any
fallback face whose GSUB script list holds dev2 or deva, and then
asserted that Ka takes its half form. A face with the script tag and
no half form for Ka failed the test, although the text was shaped in
the fallback face as the test checks.
The test now takes a fallback face only when the face lists dev2 or
deva and Ka + halant + ZWJ + Ssa set in that face alone starts with
Ka's half form and ends with Ssa. It prints SKIPPED when no installed
face does. A new test runs the filter on two faces built in code that
both list dev2. It takes the face with a half feature and passes
over the face without one.
Shrink Text to Fit scales area type down at layout time, and the canvas,
PDF export and the exports that write type as outlines draw it at that
size. SVG export wrote the live text at its stored font size, letter
spacing and baseline shift, so a viewer drew it larger than the canvas
does. Legacy .ai saves wrote the stored size, leading and baseline shift
into the text objects, DXF export took the TEXT heights from the stored
size, and the CSS Properties panel gave the stored font size, letter
spacing and line height.
The text crate's scaled, which the layout scales shrunk text with, is
now public. SVG export, legacy .ai saves and the CSS Properties panel
take the type's styles from it at the layout's fit scale, and DXF
export multiplies the TEXT heights by that scale. Positions and
textLength in SVG still come from the layout.

Optical Margin Alignment and Roman Hanging Punctuation hung punctuation
in point and area type only. Type on a path kept its first and last
glyphs inside its brackets with either option on.
When Optical Margin Alignment is on, or the first paragraph has Roman
Hanging Punctuation on, the glyphs at the ends of left-to-right type on
a path now hang outside its brackets by the same amounts, measured
along the path. The type hangs at the start bracket when its line is
placed there, hangs at the end bracket when the line is placed there,
and hangs at both when it is centered. Glyphs that hang past the end
bracket do not make the type overflow. On an open path a hang stops at
the path's end, and on a closed path the two hangs together take at
most the stretch between the end and start brackets. SVG export writes
type on a path that hangs as outlines, with a warning.

The reference app justifies Arabic text with kashidas, set per paragraph
with the Paragraph panel's Insert Kashidas list (None, Short, Medium,
Long, Stylistic). VectorCraft had no kashidas, so a justified Arabic
line was spaced out at its word spaces like a Latin one.
The Paragraph panel, with the Indic options shown, now has Insert
Kashidas. On a justified horizontal area type line that is shorter
than its measure, each Arabic word with joined letters gets one kashida
between its last pair of them, drawn as tatweels (U+0640) in the font
of the letter after it. The kashidas share the line's room equally,
each at most a quarter of an em (Short), half an em (Medium) or an em
(Long); a Stylistic kashida is a row of the font's own tatweels, up to
an em. The word spaces take the room the kashidas leave, so the line
keeps its width, and line breaks do not change. The letter after a
kashida advances over it, so the caret before that letter, a selection
of it and a click on it take the kashida in. None, the default, leaves
lines as they were.
In horizontal type that is not on a path, the caret in a letter drawn
with several glyphs (a letter with a vowel mark) is now placed by the
whole letter, as hit testing already measured it, instead of by its
first glyph.
text.setFormat takes kashida. The setting is saved with the paragraph
only when it is not None, paragraph styles carry it, and Reset Panel
sets it back to None.

The composer offered a break after a dash, a Thai word or a space even when
a space came next, so it could start the next line with that space. A
leading space makes the next line wider, and the composer could score that
break better. With mixed type sizes now composed in rectangular area type,
Thai text whose words come from a Thai font broke as "สวัสดีครับ" and
" ภาษาไทยง่าย". The composer now offers only the break after the spaces,
as the single-line composer ends its lines.
A paragraph with one character in a different type size was broken
with the Single-line Composer, even when Every-line was chosen: the
composer gave up whenever the paragraph's glyphs did not all have the
same line metrics (ascent, descent, leading, cap height, x height and
em box top).
In rectangular area type without text wrap, rows and columns included,
the width of a line does not depend on how far down the frame it is.
There the Every-line Composer now composes a paragraph whose
characters differ in line metrics (type size, font, leading or
vertical scale, or an inline graphic taller than the text), and each
line takes its height from its own text, as with the Single-line
Composer. Area type of another shape, or with text wrap, still breaks
such a paragraph with the Single-line Composer.

style_weight reads W0–W9 style names (Hiragino, Morisawa…) as their weight classes before the English words, so SVG and CSS export write font-weight 600 for W6, and nearest-style matching weighs them too.
Font services (NexusFont, Adobe Fonts) register faces with the OS without
touching font-folder mtimes; only re-asking the platform lister sees them.
Check every two seconds as well as on window focus, and test that path churn
is detected on the system font scan.

The Paragraph panel menu's Justification… was a disabled stub, and justified
lines stretched word spaces between fixed limits (80% to 150%).
Each paragraph now has Justification options: Word Spacing, Letter Spacing
and Glyph Scaling (Minimum, Desired, Maximum, in percent), Auto Leading and
Single Word Justification. Desired applies to every line; a justified line
fills its measure with word spacing first, then letter spacing, then glyph
scaling, each within its range, and past them its word spaces take the
rest. The Every-line Composer scores lines by that flexibility. Auto
Leading sets the leading of characters whose leading is Auto. A justified
line holding one word is spread between its letters (Full Justify) or
aligned left, centre or right.
The defaults are the documented ones (80/100/133, 0/0/0, 100/100/100, 120,
Full Justify), saved only when they differ. Because the default maximum
word spacing is 133%, justified paragraphs break differently than before;
the Every-line Composer's second pass is now unbounded for justified text
(it used to give up past four times the stretch and fall back to the
Single-line Composer, which the narrower default range would make common),
and lines that can't stretch at all are still refused.
text.setFormat takes wordSpacing, letterSpacing, glyphScaling ([min,
desired, max] or {min?, desired?, max?}), autoLeading and
singleWordJustification; Minimum ≤ Desired ≤ Maximum must hold or nothing
changes. Paragraph styles carry the options (New and Redefine capture
them), and Reset Panel resets them. Justification… opens a dialog
(ui.justification) with Preview; OK is disabled while a row is out of
order. Live SVG text places characters the options move, and a glyph that
Glyph Scaling scales is stretched to its width; PDF uses the glyphs'
transforms. Vertical type isn't glyph scaled; type on a path doesn't use
the options.

In type that holds right-to-left characters, Left and Right move the
caret through the visual caret stops (`caret_horizontal`). A cluster
drawn with no advance, such as a zero width non-joiner that the font
shapes as a glyph of its own, puts two stops at one x. A step kept the
stop with the lower byte, and the next step passed over the other one,
so the arrow keys never reached it. In Persian میخواهم laid out on
macOS, the caret could not be put between the non-joiner and خ with
the arrow keys.
Stops at one x are now visited one at a time in byte order. Going
right, the caret takes them in increasing order on left-to-right
glyphs and in decreasing order on right-to-left glyphs; going left,
it takes them in the reverse order. The end of a soft-wrapped line,
which the caret shows on the next line, is not one of those stops.
Where no two stops share an x, a step goes where it went before.
The Paragraph panel menu's Roman Hanging Punctuation was a disabled stub.
It is now a per-paragraph attribute: in a left-to-right paragraph of point
or area type with it on, the punctuation Optical Margin Alignment hangs
(quotation marks, hyphens, full stops and commas wholly; asterisks,
tildes, ellipses, en and em dashes, colons and semicolons by half) hangs
outside the margin when it starts or ends a line, on the same sides
(left-aligned lines at their left, right-aligned at their right, centered
and justified at both); letters don't hang. With Optical Margin Alignment
on as well, letters hang too. East Asian punctuation keeps hanging only
through burasagari. The layout shares Optical Margin Alignment's hanging
code, given the share of each glyph that hangs.
text.setFormat takes romanHangingPunctuation; it is off by default, saved
only when on, carried by paragraph styles (New and Redefine capture it)
and turned off by Reset Panel. The panel menu item is a checkbox enabled
with type selected.

VectorCraft listed a variable font's named instances as styles, but
type could not be set between or past them. The reference app's
Character panel has a Variable Font control that adjusts a variable
font's axes, such as Weight, Width and Slant.
Type now keeps Variable Font settings by axis tag
(CharStyle::font_axes, saved as fontAxes only when set). text.setFormat
and text.setRangeStyle take fontAxes: each value is clamped to its
axis's range, a tag the font has no axis for is left out, and null
goes back to the style's own setting. Another font or style clears
them, including one from a character style that does not set them. A
character style captured from type sets them, with {} for none.
text.fontList {family, style} lists a font's axes.
Layout, outlines, the substituted-glyph highlight and PDF export use
the font instanced at the settings, and neighboring runs at different
settings are shaped apart, as runs in different fonts are. SVG export
writes them as font-variation-settings, the wght setting as the weight
and the wdth setting as font-stretch, and embeds the font instanced
there; SVG import reads font-variation-settings back. Legacy .ai export
warns that the settings are left out.
The Character panel shows a Variable Font button for a variable font.
It opens a slider and a field for each axis the font does not hide,
labeled with the font's name for the axis, and screen readers get each
slider under that name. A drag is one undo step. Reset Panel leaves
the settings, as it leaves the font and style.
Missing Glyph Protection now keeps the settings and the font version
on the characters that keep their font; before, it kept only the
family and style. A character style applied or redefined with another
font now clears the old font's version, as text.setStyle does, unless
the style sets one. SVG export with embedded fonts warns when faces of
one weight, style and width share characters, which browsers then draw
in one of the faces.

Type › Optical Margin Alignment was a disabled menu item. The reference
app's Optical Margin Alignment hangs Roman punctuation and the edges of
letters such as W and A outside the margins of every paragraph of a
type object.
type.opticalMarginAlignment (Type › Optical Margin Alignment) turns it
on or off for the selected type in one undo step, and the menu item is
checked while the type has it on. In every left-to-right paragraph of
point and area type, quotation marks, hyphens, full stops and commas at
a line's start or end hang wholly outside the margin there. Asterisks,
tildes, ellipses, en and em dashes, colons and semicolons hang by half
their width, and A, V, W, Y, v, w and y hang by a tenth of theirs. A
punctuation mark followed by a quotation mark hangs with it.
Left-aligned lines hang at their left margin, right-aligned lines hang
at their right margin, and centered and justified lines hang at both.
Lines break where they did before, and the space that justification
adds between glyphs leaves out the gaps next to a hanging punctuation
mark.
The setting is off for new type and for documents from before it, and
the type object saves it only when it is on.
The Type menu's checks for Optical Margin Alignment, Type Orientation
and the Type on a Path effects now read the type inside a selected
group, as the commands do.
Docs: docs/mcp.md, docs/target-app-parity.md, docs/type-parity.md.
Each style run was shaped on its own, so restyling one character, even
only its fill, dropped the font's kerning pairs at the new run
boundaries. A fill change on the V of 40 pt "AVAV" moved it 0.56 pt and
moved the characters after it 1.12 pt. Manual kerning on a character
also dropped the font's kerning with the character before it.
Adjacent runs that differ only in fill, stroke, underline,
strikethrough, overprint, character style name, leading, baseline
shift, rotation, Character Alignment, kerning, or tracking (as long as
both values leave standard ligatures on or both turn them off) are now
shaped together, and each glyph takes those attributes from its own
run. The font's kerning pairs apply after characters with automatic
kerning: a manual value replaces the pair after its character, and the
pair before it stays, except before a character that All Caps or Small
Caps sets as two letters (ß as SS). A change of font, size, scale or
OpenType features still shapes the characters apart, and a ligature or
a mark still does not join characters in different styles.

A syllable drawn with several glyphs that share one cluster, such as a
pre-base i matra and its consonant (कि), had a caret stop at the edge
of each glyph. A click just right of the matra, in the left half of
the syllable, put the caret after the syllable. byte_in_line now takes
one extent for each cluster, and type on a path compares the click
with the middle of the cluster, from the start of its first glyph to
the end of its last.
New tests with an installed OpenType Devanagari font check that क्ष
forms one conjunct glyph, that र्क draws the reph after its base, that
कि draws the matra before its consonant, that Ka with a nukta matches
the precomposed क़, and that each syllable is one cluster with the
arrow keys stopping at its ends. They print SKIPPED when no such font
is installed.

A tab's width depends on where it falls from the tab origin. Line breaking and the line width measure it from the left edge, but a centred or right aligned line is placed from its own start, so its tabs stopped elsewhere. The line is now laid out with its tabs measured from the left and then aligned as a whole.

Line breaking, the line's natural width (and so justification) and the composer counted a tab as its glyph's width, a space, while it is set up to its next tab stop. A paragraph starting with a tab, as in the report, filled a justified line as if the tab were one space, and the line ran past the frame. break_line and the line width now measure tabs with tab_advance, and a paragraph with a tab is broken line by line, since the composer works with fixed glyph widths.

The Paragraph panel menu's Hyphenation… was always disabled, and
automatic hyphenation used fixed limits: words of 6 letters or more,
3 letters on each side of the hyphen, any number of hyphenated lines
in a row, and capitalized words hyphenated.
Each paragraph now has hyphenation options: Words Longer Than, After
First, Before Last, Hyphen Limit, Hyphenation Zone and Hyphenate
Capitalized Words. The defaults are the fixed limits, and documents
keep their line breaks. The options are saved only when they differ
from the defaults. text.setFormat takes wordsLongerThan, afterFirst,
beforeLast, hyphenLimit, hyphenationZone and hyphenateCapitalized, and
paragraph styles carry the options. Hyphen Limit applies with both
composers. Hyphenation Zone applies with the Single-line Composer: a
line whose text before the next word already ends within the zone
breaks before that word instead of hyphenating it.
Hyphenation… is enabled with type selected and opens a Hyphenation
dialog (ui.hyphenation) on the values the Paragraph panel shows. OK
runs text.setFormat with the values that changed, as one undo step.

An ideographic space in a face without U+3000 was shaped with that face
and could set at zero width, removing an indent. Only what the layout
handles itself (tab, line and paragraph breaks) stays with the primary.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
When type had used a font, removing the font while the app ran left
it in the font menus, and the type kept drawing in it until the app
restarted. The font list is the loaded faces plus the scanned catalog,
and a scan replaced the catalog but kept every loaded face.
A scan now drops each loaded face whose file it did not catalog, with
the face's cached outlines. A family with no face left leaves the font
lists, and type set in it lays out in the fallback font and is
reported missing, as when a document opens without the font. When the
font is installed again, the next scan lists it and the type draws in
it again. Bundled fonts and fonts added as bytes have no file and
stay.
Docs: docs/mcp.md, docs/target-app-parity.md.
The nine OFL faces in `assets/fonts` are compiled into every build of
vectorcraft-text: 3.4 MB of the binary, about 1.6 MB of a gzipped wasm.
An embedder that loads every font at run time with `FontDb::add_font`
(a web app serving its own font catalogue, say) ships them twice and
can't turn them off.
- vectorcraft-text: `bundled-fonts`, a default feature, holds the
`include_bytes!` list. Off, a database starts without them (craft-fonts
and system fonts are unaffected) and text has no glyphs until a font
is added, as when the bundled fonts fail to parse.
- vectorcraft-engine: a `bundled-fonts` default feature forwards to it,
so the apps and any embedder using the engine keep the fonts unless
they build it with `default-features = false`.
- The workspace declares vectorcraft-text without default features, so
no library crate turns the fonts back on. The tests of cad, metafile
and tools, which lay type out, ask for the feature in their
dev-dependencies; the other crates' tests get it through testkit.
`cargo test --workspace` builds with the fonts, as before. A new
integration test, `without_bundled_fonts`, covers the configuration
without them (`cargo test -p vectorcraft-text --no-default-features
--test without_bundled_fonts`): the database starts without them, text
in no font lays out with no glyphs, and a font added later is used and
is the fallback for families the database lacks.

For Auto Size area type in columns, every text edit, each keystroke of
the Type tool included, laid the text out in one column and then laid
the columns out at that height and at each step of a bisection for the
least height that holds the text. In the release-build timing test
auto_height_in_columns_typing_timing (stories of 5,000 to 50,000
characters at 9 pt in a frame 500 pt wide), a keystroke laid the
columns out 18 to 22 times, and typing at the start of the story of
50,000 characters in 2 columns took 1,670 ms a keystroke.
The bisection now runs on the lines of the one-column layout.
columns_hold computes where those lines would sit in the columns, with
each column's first line at its first baseline below the column's top
(LineInfo::first_baseline, new in vectorcraft-text). The columns are
then laid out at the upper height the bisection ends on and, when they
hold the text there, at the lower one, unless that is the 1 pt it starts
from. When they hold the text at the upper height and not at the lower
one, Auto Size takes the upper height. When taller columns always hold
the text, the old search ends between the same two heights. When the
text wraps around other objects or does not fit the one-column layout,
or when that check fails, the columns are laid out at every step as
before. The same keystroke now takes 292 ms.
Docs: docs/target-app-parity.md.
In a dev build, opening a native file whose area type has 2^60 rows
or 2^60 columns failed with an internal error ("capacity overflow"),
and opening one with 2^32 rows and 2^32 columns failed with "attempt
to multiply with overflow". Text layout reserved room for rows times
columns frame cells. `text.areaOptions` keeps both counts within 1 to
100, but reading a document kept the counts the file gave.
Reading a document now clamps each count to 1 to 100
(`AreaOptions::MAX_ROWS_COLUMNS`): a larger count reads as 100, and 0
reads as 1, as layout already treated it. Text layout clamps both
counts the same way. Area type with 1 to 100 rows and columns lays out
as before.
The cells of a frame now share one copy of the frame's flattened
polygons and one copy of the flattened text wrap shapes. Each cell held
its own copy: in a dev build, a test process that laid out text in 100
rows and 100 columns of a circle frame of radius 1,000,000 pt peaked at
1.33 GB of memory, and now peaks at 100 MB.
Type is written as version 7 text objects (§15): point type, area type and type on a path, with
fonts by PostScript name re-encoded to Windows-1252, and each run's paint, size, scaling,
tracking, leading, alignment and indents; type 8-bit text can't hold (or all, with outlineText)
is outlines. The format hides only layers, so hidden objects go to a hidden layer above their
own (hiddenObjects "layer", the default), are left out ("omit") or show ("visible"). The .ai
reader reads legacy type (To … TO, TE, %AI3_BeginEncoding) and ignores Ar; the import fuzzer
gets legacy type tokens.
