* Text: input method composition as commands, one undo step per composition (#101) text.compose shows an input method's preedit in place at the insertion point and replaces it on each update; an empty preedit cancels and restores the text and selection. text.commit replaces the composition with the result as one undo step. Any other edit, key or click settles an open composition first. The composition is underlined under the baseline (thicker under the part being converted), and the caret line is measured for empty placeholders too.

Interface text in scripts the interface fonts lack (Hangul, Simplified Chinese, Thai...) borrows faces from the font database (installed fonts such as Malgun Gothic; nothing bundled): file names, titles, notes, outline, sections, comments and typed text. Ported and widened from WordCraft's #565/#840 fallback. The notes pane keeps text typed before focus leaves in the same frame (Escape, another slide). Control channel: ui.ime.

Localization parity with PowerPoint
Last reviewed: 2026-10-10 · Last updated: 2026-10-12 · Change: minor (IME composition and CJK interface text, #101; previous: major, created; string count measured from source, PowerPoint's localizations read from its bundle) · Target: Microsoft PowerPoint for Mac 16.113 (Microsoft 365)
DeckCraft's interface is English only today: strings are literals in the UI and engine code, with no catalog and no language switch. Requests: #15 (follow the system language), #30 and PR #34 (Ukrainian, open). Dimension score: ~8% ready (estimated: English complete, slide-text script support partly there), 55–90 h to parity plus native-speaker review.
How the numbers are measured
- UI strings: ~1,050 user-visible string literals (measured 2026-10-10: distinct
capitalized literals in
crates/ui-egui/src,crates/engine/src/cmdandcrates/model/src, including the 226 command labels). A catalog will refine the count; until then percentages are against this figure. - Script support is about slide text (what users type and import), separately from the UI:
bidi and shaping live in
crates/text(UAX #9, HarfRust, UAX #14 line breaking). - PowerPoint's languages:
Contents/Resources/*.lprojin PowerPoint 16.113.4: 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 (Brazil), pt_PT, ru, sk, sv, th, tr, zh_CN, zh_TW (26 languages). PowerPoint for Mac has no Hindi or Vietnamese UI; PowerPoint for Windows has both.
The twelve key languages
| Language | Code | UI strings translated | Dialogs / tooltips / help | Script support (slide text) | Native review | Status | PowerPoint for Mac UI | Hours to full |
|---|---|---|---|---|---|---|---|---|
| English | en | ~1,050 / ~1,050 (100%) | yes / yes / no help | full | yes | full | yes | 0 |
| Simplified Chinese (Mandarin) | zh-Hans | 0 (0%) | no | renders with system CJK fonts (asset policy excludes Noto CJK from builds); UAX #14 breaking; IME composition (#101); no true vertical layout | no | none | yes | 6–10 (incl. IME) |
| Spanish | es | 0 (0%) | no | full (Latin) | no | none | yes (es, es-MX) | 3–5 |
| Hindi | hi | 0 (0%) | no | Devanagari shaping through HarfRust, untested; no bundled Devanagari font | no | none | no (Windows only) | 4–7 |
| Arabic | ar | 0 (0%) | no | bidi, contextual shaping, kashida justification, RTL bullets and caret (#4); UI not mirrored; browser export shows boxes (#81) | no | none | yes | 10–16 (incl. UI mirroring) |
| French | fr | 0 (0%) | no | full (Latin) | no | none | yes (fr, fr-CA) | 3–5 |
| Portuguese | pt | 0 (0%) | no | full (Latin) | no | none | yes (pt-BR, pt-PT) | 3–5 |
| Indonesian | id | 0 (0%) | no | full (Latin) | no | none | yes | 3–5 |
| Japanese | ja | 0 (0%) | no | renders with system or craft-fonts Japanese faces; IME composition (#101); vertical text is rotated, not laid out vertically | no | none | yes | 4–7 |
| German | de | 0 (0%) | no | full (Latin) | no | none | yes | 3–5 |
| Korean | ko | 0 (0%) | no | system Hangul fonts, in the interface too; IME composition (#101) | no | none | yes | 4–7 |
| Vietnamese | vi | 0 (0%) | no | stacked diacritics through HarfRust | no | none | no (Windows only) | 3–5 |
Other languages shipped: 0 (Ukrainian is in review as PR #34). PowerPoint for Mac ships 16 more than the twelve above: Czech, Danish, Greek, Finnish, Hebrew, Hungarian, Italian, Dutch, Norwegian, Polish, Russian, Slovak, Swedish, Thai, Turkish and Traditional Chinese.
Per-language hours assume the infrastructure exists: 8–14 h once for a string catalog (copy a
sibling app's approach, e.g. EffectCraft's menu and panel catalogs), a language setting that follows
the system (#15), plural and number formatting, and an xtask check that every key has a
translation. IME composition landed with #101 (slide text, notes and text fields; one undo step
per composition); the hours that included it are kept until the next re-measure.
Proofing languages
PowerPoint checks spelling in dozens of languages and lets each run carry a proofing language.
DeckCraft keeps a:rPr/@lang on round trip but its spelling check is a small English list of
common misspellings (crates/engine/src/cmd/review.rs); see gaps.md.
