05c8ab3b3e M14: Telugu (తెలుగు) interface language (#349)
* M14: Telugu interface font

- The interface takes `Telu` faces from craft-fonts after the CJK and Arabic ones, on the web too
- Test: Telugu text has glyphs in every family and its conjuncts are shaped

* M14: Telugu interface language

- Complete te catalog: 1,984 entries plus whole-phrase Undo/Redo; te and te_IN locales use it
- Undo and Redo labels use a catalog phrase when the language has one (Telugu puts the verb last)
- Tests, docs, attribution, parity and ROADMAP

* M14: catalog contexts for labels with two meanings

- tl_ctx! gives the signature pad's Type, the Action Wizard's Start and the comment menu's Edit their own context; Telugu translates them, other languages keep their current translation
- Preferences' All tools goes through the catalog in every language

pdfcraft-fonts

Layer L2. Font helpers for the appearance streams PdfCraft generates (comments, form fields).

Today it holds what generated appearances need without a font program:

  • helvetica_width: an approximation of Helvetica's proportions by character class. No metrics file or font program from any vendor is bundled; widths are PdfCraft's own estimates, good enough for line breaking and alignment, not for typesetting.
  • wrap: greedy line breaking with that measure (paragraphs on newlines, long words split).
  • win_ansi: Unicode → WinAnsiEncoding bytes (? for characters it can't represent), and literal to write bytes as a PDF literal string.

It also holds the fonts of the optional craft-fonts build input. build.rs embeds them as CRAFT_FONTS when the build sets CRAFT_FONTS_DIR=<checkout> (and fails if it can't while CRAFT_FONTS_REQUIRED=1, as releases set). Without that variable CRAFT_FONTS is empty and everything below copes:

  • ui_japanese_fonts: the Jpan faces for the interface, BIZ UDPGothic first.
  • ui_chinese_fonts: the Hans faces for the interface, in manifest order (without one, Chinese characters the Japanese faces lack show the replacement glyph).
  • ui_cjk_fonts(prefer_hans): both in fallback order for the UI language (Chinese group first in Chinese mode, so one line never mixes faces with different vertical metrics).
  • ui_arabic_fonts: the Arab faces for Arabic-script interface text (file names, document titles), in manifest order.
  • ui_telugu_fonts: the Telu faces for Telugu interface text (the Telugu catalog, file names, document titles), in manifest order.
  • document_japanese_font / japanese_glyph: the face (Shippori Mincho, then BIZ UDMincho) whose outlines become the Type 3 fallback font for Japanese text written into PDFs. Without it, japanese_glyph returns GlyphError::NoFont and the editor reports a clear error.
  • SHIPPORI_MINCHO: Shippori Mincho's bytes, or None.

wasm32 builds embed only BIZ UDPGothic Regular and any Arab or Telu face, to keep the web build small: the web build currently has no Chinese face, so Chinese there still shows the replacement glyph. Font files are never committed here (AGENTS.md §1.4; team members: craftrules standards/fonts.md, internal).

The full font subsystem (parsing, shaping, subsetting and embedding) arrives with M2.2/M7.
