A string without a translation shows in English, and an empty catalog row counts as untranslated. Tests keep duplicate-key and placeholder checks and the lookup, context, plural-caption and right-to-left mechanics; coverage, stale-key, wording and per-language literal checks are removed. `cargo xtask i18n-report`, also a `cargo xtask ci` step, runs the ignored missing_translations_report test and prints the missing strings per language.

Localization parity
Last reviewed: 2026-10-11 · Last updated: 2026-10-23 · Change: minor (missing translations are reported, never a failure; catalog counts remain the 2026-10-10 measurement) · Target: Adobe InDesign 2026 (21.6)
Per-language status of the DesignCraft interface and of document typesetting in each script. Script-specific typesetting detail: cjk.md, cjk-typography.md, arabic-typography.md. Overall numbers: target-app-parity.md.
Dimension score: ~45% ready (estimated), 120–180 h plus native-speaker review (human).
How it was measured
Interface strings live in crates/ui-egui/src/i18n.rs (a shared table with German, French,
Spanish, Japanese and Simplified Chinese columns) and crates/ui-egui/src/i18n/{ar,cs,it,ja,ka,pt_br,uk}.rs.
Untranslated strings fall back to English. A script (2026-10-10) built the set of English
interface strings as the union of every catalog's keys, every engine command label and every
literal passed to tr/t in the UI crate: 1,724 strings. A further ~145 capitalized literals
in the UI crate appear in no catalog (some are test data or proper names), so the true total is
somewhat higher and every percentage below is a slight overestimate. Help: DesignCraft has no
help content in any language (Help ▸ opens the project's pages).
A missing translation never fails a test, a build or a release. cargo xtask i18n-report (also
a step of cargo xtask ci, so the list is in every gate log) prints how many interface strings
each language lacks, then the strings.
InDesign 2026 ships 25 interface localizations (.lproj folders: cs, da, de, el, en, en_GB, es,
fi, fr, hu, it, ja, ko, nb, nl, pl, pt, ro, ru, sq, sv, tr, uk, zh_CN, zh_TW); Arabic and Hebrew
come as Middle East editions with an English or French interface and right-to-left features.

Percentages are of the 1,724 measured strings. A language is full only when every user-visible
string is translated and its script renders and edits correctly; none but English is.
Japanese follow-up (2026-10-11): print ranges, imported style handling, the built-in (import)
caption, table row/column movement and row-height distribution now use the existing translation
catalog. Print, import options and an active table were rendered in Japanese and English with
craft-fonts. The language totals above retain their dated measurement; this is a targeted fix.

DesignCraft ships 5 interface languages beyond the twelve; InDesign ships 17 beyond its eight of the twelve (cs, da, el, en_GB, fi, hu, it, nb, nl, pl, ro, ru, sq, sv, tr, uk, zh_TW).
Document languages
InDesign 2026 hyphenates and spell-checks ~40 languages (Hunspell and Duden dictionaries). DesignCraft hyphenates English, Spanish, Portuguese and Norwegian and spell-checks English only. Text language can be set per paragraph and character (Properties, Character panel) and drives quotes and locale shaping. See typography-parity.md.
