Optical Margin Alignment was stored and set per text object, so the frames of one thread could differ. Turning it on in the first frame of a thread left the lines in the other frames flush with their margins. Type › Optical Margin Alignment and type.opticalMarginAlignment now set every frame of a selected frame's thread, in one undo step, and the reply's ids list them all. After any edit to a thread, its frames take the setting of the frame that the edit turned on or off, else the first frame's. Threading frames gives the thread its first frame's setting, and frames taken out of a thread keep it. A file whose frames of one thread differ opens with the first frame's setting in all of them. This holds for native files and for documents restored from the editing copy that an EPS, SVG, PDF or .ai file carries. Threading text from an out port into existing area type (text.thread.add with to) now flows the story into that frame at once. Before, the story reached it only at the next edit of one of the thread's frames. Docs: docs/mcp.md, docs/target-app-parity.md, docs/type-parity.md.

Type is Illustrator's largest single area by use (weight 13 of 105 across "Type core" and "Type advanced" in
target-app-parity.md). This checklist lists the features one by one. Status is from the
code and tests (crates/text, crates/engine/src/cmd/type*.rs, textstyles.rs, crates/tools/src/text.rs)
against Illustrator's public documentation; estimated unless noted.
Summary
| Part | % | Remaining (h) |
|---|---|---|
| Type core (point, area, path type, Character/Paragraph, styles, threading, OpenType, fonts) | 80% | 14–19 |
| Type advanced (CJK composition, Middle Eastern, spelling, Touch Type, Retype, variable fonts) | 50% | 20–28 |
Checklist
| Feature | Status | Notes |
|---|---|---|
| Native font-family labels | partial | With Show Font Names in English off, localized legacy names are used when typographic names contain no native label (#2208); loaded-font and catalog-only regressions. Choosing among multiple native languages is unchanged. |
| Point, area and type-on-a-path type; vertical variants | done / partial | vertical point, area and path type have initial support; fullwidth ！ / ？ keep the nominal glyph upright when no vertical alternate exists (Unicode Tu); in a non-rectangular area a word too wide for the top lines moves down to the first line that holds it (#1615); Escape while typing ends the edit, keeps the type selected and switches to the Selection tool (#1802); text.create and text.createInPath take justify (#1752); MCP add_text forwards vertical to both commands |
| Area Type Options (rows, columns, inset, first baseline, Auto Size, Shrink Text to Fit) | done | the commands that make or restyle type say when it does not fit its frame; MCP add_text takes Auto Size and Shrink Text to Fit (#1471) |
| Threaded text, Fit Headline, Text Wrap | done | Fit Headline sees wrapping in a frame one line tall (#1444) |
| Threading from the out port: a click on the red "+" loads the text; a click on a closed path or area type threads into it, a click on empty canvas makes a frame of the same shape and size there, a drag draws a rectangular frame; Escape or another tool cancels | partial | #2572 in part: the Selection tool, text.thread.add {from, to?, rect?, at?}; only the red port of overflowing area type is clickable (empty ports and in ports are not drawn, so they can't be clicked yet), type on a path doesn't thread, and the loaded cursor borrows the I-beam until it's drawn |
| Type on a Path effects and options; brackets | done | #429 |
| Character and Paragraph panels, styles with overrides | done | Character-style Auto-leading resets, partial definitions, local leading overrides, override markers, Undo/Redo and native serialization have regression coverage; differing paragraph alignments leave the shared alignment buttons unselected (headless regressions, full integration CI and visual review pass); mixed-value display for other paragraph fields remains missing |
| Character size and horizontal scale after object/group scaling | done | #1034: fields and setters compensate the stored affine; point size follows the transformed em-height axis, not the glyph ink bounds. Range edits, keyboard increments, leading and baseline shift use document points; rotation, reflection and shear remain editable. |
| Preserve font sizes while scaling a group | missing | Separate enhancement; scaling still scales text with the other artwork. |
| OpenType panel, Glyphs panel, alternates | done | Highlight Alternate Glyphs preference (#394, off by default) paints pink behind OpenType substitutions on screen when on; stylistic sets ss01–ss20, stylistic and titling alternates, proportional and lining figures, superscript and subscript are character-style features (text.setStyle {features}, #1607) |
| Font menu: samples, live preview, filters, favourites; font matching by any name; Find Font | done | #339; script filter: Japanese, Latin, Thai; the font scan on Linux also reads the folders fontconfig's configuration lists, such as TeX fonts under /usr/share/texmf/fonts (#1548, fixes #1529; not verified on Linux) |
| Missing glyphs set in an installed font made for their script (Thai, Lao, Khmer, Myanmar first; then any font that has them) | done | Thai: Leelawadee UI, Tahoma, Thonburi, Sukhumvit Set, Noto Sans Thai, TLWG |
| Full font-name matching (OpenType name ID 4) | done | #1258: loaded/cataloged faces and Missing Fonts searches; localized names and variable default faces; Windows font-service QA pending |
| Variable fonts | partial | named instances as styles; Character panel › Variable Font sets each axis (fontAxes); the font menu's Variable filter is missing |
| Fallback glyphs keep the text's weight and slant | done | #2491: a character from a fallback face is set in that family's face nearest the run's weight and slant; Bold Italic of a missing family is drawn Bold (Source Sans 3 has no Bold Italic) rather than Italic |
| Colour fonts (OpenType SVG / COLR) | partial | |
| Every-line and Single-line composers | done | tuned by eye, never compared side by side |
| Optical Margin Alignment | done | Type › Optical Margin Alignment, type.opticalMarginAlignment: per type object, with one setting for all the frames of a thread, in point and area type of left-to-right paragraphs; type on a path and right-to-left paragraphs do not hang |
| Optical Margin Alignment | done | Type › Optical Margin Alignment, type.opticalMarginAlignment: per type object, in point and area type of left-to-right paragraphs; type on a path and right-to-left paragraphs do not hang |
| Roman Hanging Punctuation | done | Paragraph panel menu › Roman Hanging Punctuation, text.setFormat {romanHangingPunctuation} (#2756): per paragraph, Optical Margin Alignment's punctuation and amounts without the letters; paragraph styles carry it. Evidence: tests::roman_hanging_punctuation_hangs_punctuation_but_not_letters, typecmd::area_tests::roman_hanging_punctuation_is_set_per_paragraph_and_saved_only_when_on |
| Hyphenation… and Justification… options | partial | Hyphenation… (ui.hyphenation, text.setFormat) sets each paragraph's Words Longer Than, After First, Before Last, Hyphen Limit, Hyphenation Zone (Single-line Composer only) and Hyphenate Capitalized Words, and paragraph styles carry them (#2310); Justification… missing (menu stub) |
| Tab stops and leaders; Tabs panel | partial | Tabs panel and stops with leaders in the model (text.tabs.set); a stop drags from where the press landed (#1458); leaders fill the tab's gap, repeated on a grid so they line up from line to line (#1877) |
| Hidden characters (Show Hidden Characters) | done | type.hiddenCharacters |
| Spell check (Check Spelling, Auto Spell Check, custom dictionary) | missing | menu stubs; needs an openly licensed dictionary |
| Smart Punctuation, Change Case, Find & Replace | done | |
| Caret: the arrows and Delete step over whole clusters (Thai consonant with its marks, combining accents, emoji); Backspace removes one character | done | |
| Touch Type tool | done | moves, scales and rotates one character through its kerning, baseline shift, scales and rotation (text.touchType); the first character of a line and right-to-left characters move only up and down |
| Retype (identify fonts in outlines/images) | missing | Illustrator's uses a cloud model |
| Snap to Glyph | missing | menu stub |
| Thai, Lao, Khmer, Myanmar: shaping (marks, reordering), lines broken between words, word-by-word caret and double-click | done | words found by ICU4X's line segmenter: dictionaries on the desktop, LSTM models on the web |
| Middle Eastern: bidirectional layout, Paragraph Direction | done | |
| Middle Eastern: digit types (Character panel menu › Digits: Default, Arabic, Hindi, Farsi) | done | text.setFormat / text.setRangeStyle {digits}; the text keeps the typed digits, the glyphs and SVG export follow the style |
| Middle Eastern: Character Direction, kashidas, Middle Eastern composers, split caret | missing | |
| CJK: input methods (marked text, candidate window) | done | |
| CJK: kinsoku (Hard, Soft, None), Line-end Punctuation Half Width, tate-chu-yoko (auto) | done / partial | custom kinsoku sets, the Mojikumi Settings dialog and the other mojikumi sets missing |
CJK: Proportional Metrics (palt in horizontal type, vpal in vertical type) |
done | #966 |
| CJK: ruby, manual tate-chu-yoko | missing | #633 |
| Inline symbols in text | beyond Illustrator | not scored |
| Align Stroke (inside, outside) on live type's character stroke | beyond Illustrator | not scored; stroke.set {align} and text.setRangeStyle {strokeOptions: {align}}; saved natively, drawn around the glyphs on the canvas and in PDF, EPS and SVG (live text, stroke on the glyph outlines); visual bounds grow with it (#2294) |
Character Styles menu New/Redefine and footer New capture the first selected character of a nonempty Type selection, including exact style-run and UTF-8 boundaries; New adds a definition without applying it. New/Redefine commands accept optional end for range capture. Start-only command affinity, existing UI caret/object behavior and paragraph capture at start remain unchanged. Pointer regressions assert captured definitions, linked-text updates and local overrides, complete-document Undo/Redo and saved state, with whole-object, collapsed-caret and range-Apply controls. Capture closes prior typing while preserving the Type selection. Live text and Select All regressions exercise menu New/Redefine and footer New, asserting that further typing retains the captured definition and that typing, capture and further typing have separate Undo/Redo steps. Focused engine and egui input tests pass for boundary capture, all three live-typing capture routes and the existing compatibility controls. Full workspace CI passes.
Revision history
| Date | Change | Summary |
|---|---|---|
| 2026-10-17 | minor | Roman Hanging Punctuation (#2756): per-paragraph hanging of Latin punctuation outside the margin; scores unchanged |
| 2026-10-17 | minor | A click on area type's red out port loads the Selection tool with the overflow text; the next click threads it into a closed path or a new frame of the same shape there, a drag into a new rectangle (text.thread.add, #2572 in part). The out port moved up the frame's right side, clear of the corner handle. Scores and hours unchanged. |
| 2026-10-16 | minor | Native font-family labels fall back from English-only typographic names to localized legacy names (#2208). English labels and native typographic precedence are preserved; synthetic loaded/catalog tests. Scores and estimates unchanged. |
| 2026-10-16 | minor | Align Stroke on live type: the characters' stroke goes inside or outside the glyphs without creating outlines, for every run or a range; kept in the native file and in canvas, PDF, EPS and SVG output (#2294); beyond Illustrator, scores and hours unchanged |
| 2026-10-14 | minor | Cmd+Shift+C (Align center) works on Windows and Linux too, where egui reported it as a copy (#1940); scores and hours unchanged |
| 2026-10-14 | minor | Cmd+Shift+C (Align center) works on Windows and Linux too, where egui reported it as a copy; a double-click on area type's bottom middle handle turns on Auto Size (#1940); scores and hours unchanged |
| 2026-10-14 | minor | MCP add_text exposes the existing vertical option for point, area and path type; horizontal remains the default; scores and hours unchanged. |
| 2026-10-14 | minor | Vertical fullwidth question and exclamation marks keep their nominal glyph upright when the font has no vertical alternate; scores and hours unchanged. |
| 2026-10-14 | minor | Tab leaders are drawn: the leader's characters fill the tab's gap in the tab's font and size, whole copies on a grid from the frame's edge so leaders line up across lines (fixes #1877); scores and hours unchanged |
| 2026-10-14 | minor | Type inside symbols, pattern tiles, graph designs and opacity masks gets its layout bounds back on opening a native file, so warped type in a symbol looks the same after save and reopen (#1833, #1738). Score unchanged (estimated) |
| 2026-10-14 | minor | Escape while typing ends the edit, keeps the type selected and switches to the Selection tool (#1802, #1686, #1656); Select › Same matches type on its characters' fill and stroke (#1746, #1737); text.create, text.createInPath and the MCP add_text tool take justify, so point type can be centred on or end at its point (#1752, #1748); scores and hours unchanged |
| 2026-10-13 | minor | Area type in a non-rectangular shape moves a word too wide for the top lines down to the first line that holds it instead of breaking it (#1617, fixes #1615); Stylistic sets (ss01–ss20), stylistic and titling alternates, proportional and lining figures, and superscript and subscript glyphs can be turned on as OpenType features of a character style (text.setStyle {features}), and the OpenType panel keeps them (#1611, fixes #1607); scores and hours unchanged |
| 2026-10-13 | minor | Paragraph/Properties alignment buttons show mixed alignment without changing range commands; headless regressions, full integration CI and visual review pass; other mixed paragraph fields, scores and hours unchanged |
| 2026-10-13 | minor | The font scan on Linux also reads the folders fontconfig's configuration lists, such as TeX fonts under /usr/share/texmf/fonts (#1548, fixes #1529; not verified on Linux); scores and hours unchanged |
| 2026-10-13 | minor | Character Styles range capture samples the first selected character at run boundaries and closes prior typing; boundary and typing-history input tests and full workspace CI pass; lifecycle and range controls retained; scores and hours unchanged |
| 2026-10-13 | minor | The commands that make or restyle type, and MCP add_text, report area type that does not fit its frame, and add_text takes Auto Size and Shrink Text to Fit (#1500, fixes #1471); a tab stop in the Tabs panel drags from where the press landed, a stop just added included (#1487, fixes #1458); scores and hours unchanged |
| 2026-10-13 | minor | Fit Headline no longer pushes the tracking to its ceiling and loses glyphs when the frame holds one line (#1445, fixes #1444); text frames, wrap shapes and type paths with coordinates beyond a billion points hold no text, and layout limits its search for room, instead of hanging (#1451); scores and hours unchanged |
| 2026-10-12 | minor | Character styles retain explicit Auto leading, propagate resets and preserve local leading overrides; scores and hours unchanged |
| 2026-10-12 | minor | A character no installed font had is looked for again after the fonts are rescanned, so installing a font fixes it without a restart (#1376, from #992); scores and hours unchanged |
| 2026-10-16 | minor | Fallback glyphs keep the text's weight and slant; Bold Italic of a missing family keeps the bold (#2491); scores and hours unchanged |
| 2026-10-16 | minor | A variable font whose name table says Light but whose default instance is Regular (Noto Sans Hebrew) lists and weighs its default face as Regular (#2521); scores and hours unchanged |
| 2026-10-12 | minor | Full-name font matching and Missing Fonts searches (#1258): synthetic static/variable font regressions; Windows font-service QA pending; scores and hours unchanged |
| 2026-10-11 | minor | Middle Eastern: digit types done (Character panel menu › Digits: Default, Arabic, Hindi, Farsi; text.setFormat / text.setRangeStyle {digits}); Character Direction, kashidas, composers and the split caret still missing; scores unchanged at this rounding |
| 2026-10-11 | minor | Thai, Lao, Khmer and Myanmar words for the caret (Ctrl/Alt+arrows) and double-click; combining marks count as part of a word; score unchanged (estimated) |
| 2026-10-11 | minor | Font menu: a Thai script filter beside Japanese and Latin; score unchanged (estimated) |
| 2026-10-11 | minor | Thai, Lao, Khmer and Myanmar text breaks its lines between words (ICU4X line segmenter) instead of only at spaces; score unchanged (estimated) |
| 2026-10-11 | minor | The Type tool's arrows and Delete move by grapheme cluster, never between a Thai consonant and its vowel or tone marks; score unchanged (estimated) |
| 2026-10-11 | minor | Thai (Lao, Khmer, Myanmar) missing from the font in use falls back to an installed font made for the script instead of whichever face covering it loaded first; score unchanged (estimated) |
| 2026-10-11 | minor | Proportional Metrics done: palt in horizontal type, vpal in vertical type (#966, #1082); ruby and manual tate-chu-yoko still missing |
| 2026-10-10 | minor | #1034: transformed character controls and regression coverage; preserving group font sizes remains a separate enhancement. Scores/hours unchanged at this rounding. |
| 2026-10-10 | major | First checklist, split out of the parity table's Type core and Type advanced rows |
