Localization parity with Microsoft Word
Last reviewed: 2026-10-10 · Last updated: 2026-10-10 · Change: major (first version; catalogs measured from
crates/ui-egui/src/i18n, Word's languages from its bundle listing) · Target: Microsoft Word (Microsoft 365) for Mac 16.113.4
Interface languages, script support and proofing per language. How translation works (catalog
format, adding a language, clean-room rule): crates/ui-egui/src/i18n/mod.rs.
Dimension: ~25% (estimated), 80–130 h to full for the twelve key languages plus ~50 h for the other ~18 languages Word ships, plus native-speaker review (human).
What Word ships (measured by listing the bundle)
- 30 interface languages (31
.lprojfolders incl. Base): ar, cs, da, de, el, en, en-GB, es, es-MX, fi, fr, fr-CA, he, hu, id, it, ja, ko, nl, no, pl, pt (BR), pt-PT, ru, sk, sv, th, tr, zh-CN, zh-TW. Arabic and Hebrew get a mirrored interface. No Hindi or Vietnamese interface on Mac. - 120 proofing tools (
SharedSupport/Proofing Tools): spellers for ~50 languages, grammar checkers for ~20, hyphenators for ~16, thesauri for ~20.
What WordCraft ships (measured)
- 9 interface languages: English plus
zh-hans,zh-hant,ja,uk,es,pt-br, and Serbiansr/sr-latn(#250) (catalogs of ~930–1,010 entries each). A test (every_tab_and_command_is_translated) enforces that every ribbon tab, command label and ribbon location is translated in every language. - Of the 675 English strings a scan extracts from
tl!(…)calls and command labels/locations, each catalog covers 661 (98%). Some newer dialog and pane strings (Equation tab tooltips, Zotero, Read Aloud, Backstage greetings) aren't wrapped intl!yet, so they show in English in every language: the true share of visible strings is ~93–95% (estimated). - Pending PRs: German (#203), Norwegian Bokmål (#208) and Nynorsk (#210), Hebrew with RTL (#20).
- Proofing: English only (one dictionary, rule-based grammar, English hyphenation patterns).
- Document scripts: shaping via HarfRust (HarfBuzz port) for every script; bidi (UAX #9) and Arabic shaping tested (#207); IME on all desktop platforms (winit fixes pending, #155–#164).
