Localization parity
Last reviewed: 2026-10-11 · Last updated: 2026-10-27 · Change: minor (shared-module integration and retained localization regressions; older catalog counts retain their dated 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/table.rs (a shared table with German, French,
Spanish, Japanese and Simplified Chinese columns) and crates/ui-egui/src/i18n/{ar,cs,de,fr,hu,it,ja,ka,pl,pt_br,ru,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).
Missing translations normally fall back to English and are reported without blocking a build.
Targeted regression tests can require specific captions, such as the Data Merge arrangement
label, in every registered interface language. 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.
Hungarian follow-up (2026-10-17): hu.rs adds 1,917 entries and two context-specific
captions, including the 37 tool names. This is a partial interface catalog based on an earlier
source snapshot, not a new coverage measurement against current main. It was prepared with AI
assistance and initially reviewed by a native Hungarian contributor with over 30 years of DTP
experience; further terminology and in-context review is welcome. Preferences lists Magyar;
untranslated/new strings fall back to English. Hungarian spelling and hyphenation are separate
follow-up work and are not enabled by selecting this interface language.
Review corrections (2026-10-20) distinguish numbers from counts and text columns from grid
columns, use formal Hungarian address consistently, and align translated menu paths with
their visible labels. These corrections do not add new catalog keys or change coverage.
Test integration (2026-10-23) registers Hungarian in the shared catalog checks and restores
assertions from both merge parents. That snapshot has 1,904 entries and four context
captions after removing 11 untranslated interface-language names (the selector displays their
native names directly) and two unused internal tint keys. Seventeen live UI labels are retained
and added to the integrity test's known-label list. No used Hungarian translation was removed.
Data Merge follow-up (2026-10-25): Arrangement is translated as Elrendezés, bringing the
Hungarian catalog to 1,905 entries and four context captions. The shared all-language
arrangement check and the Hungarian catalog and toolbar tests are retained alongside the
main-branch egui API update. This is a targeted addition, not a new coverage measurement.
Georgian menu follow-up (2026-10-25): File Info… and Check for Updates… now have
Georgian catalog entries. The existing complete-menu translation assertion is unchanged.
This targeted addition retains the dated coverage figures below; the two new captions have
not had a separate native-speaker review.
Module-layout integration (2026-10-27): catalog lookup stays in i18n.rs, while the shared
table and localization tests live in i18n/table.rs and i18n/tests.rs. Menu and toolbar
regressions from both branches are retained in menus/tests.rs and toolbar/tests.rs.
Hungarian catalog contents and the dated coverage measurements are unchanged. Toolbar
coverage follows the current platform-specific keymap captions and checks a user-assigned
chord alongside translated flyout text; row sizing measures the displayed shortcut.

DesignCraft ships 6 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.

| New: Hindi, Indonesian, Korean, Vietnamese (1,724 strings, plural rules, tests) | 50–75 |
| Canvas IME (zh, ja, ko): checks by hand with system IMEs, and fixes | 10–20 |
| CJK UI font in every release build; Devanagari and Vietnamese rendering tests | 10–15 |
Catalog completeness test: every tr key and command label present in every catalog |
