Localization parity
Last reviewed: 2026-10-10 · Last updated: 2026-10-11 · Change: minor (Italian dynamic labels; previously minor: Czech review follow-ups) · Target: Adobe Photoshop 2026
Per-language status of PhotoCraft's UI. How catalogs work and how to add one:
localization.md. Language notes: Korean, Spanish,
Simplified Chinese, Italian.
How measured. cargo xtask i18n-coverage (xtask/src/i18n_coverage.rs) defines the key
universe: tl!("…") literals and trn( plurals in ui-egui (tests excluded), menu-catalog
labels and path segments, menus.rs UI commands, and engine CommandSpec labels and menu paths:
1,608 English keys on 2026-10-10. Each catalog (crates/ui-egui/src/i18n/<code>.tsv) was
checked against that universe by a source script replicating the xtask (no build). Catalogs hold
more rows than the universe because they also translate dynamic tl!(expr) strings (~159 call
sites the tool can't enumerate). Not covered anywhere: engine error and status messages and
filter parameter help, which are English in every language; so no language is full.
Photoshop 2026 ships UI language packs for cs, da, de, en, es, fi, fr (and fr-CA), hu, it,
ja, ko, nb, nl, pl, pt-BR, ru, sk, sv, tr, uk, zh-Hans, zh-Hant (24 .lproj markers; one pack is
installed per Creative Cloud install, here en_US). It has no Hindi, Arabic, Indonesian or
Vietnamese UI; Arabic and Hebrew users get English "Middle East" builds with the World-Ready
composer, and its text engine handles RTL, Devanagari and Indic scripts.
Summary. 7 of the 12 key languages at 100% of measured keys (status partial because of the
engine messages), 3 absent (Hindi, Arabic, Vietnamese), plus 8 other languages. Weighted by
speakers, ~55% ready. Remaining: 80–140 h, plus native-speaker review (none recorded for any
catalog).
The twelve key languages
| Language | Code | UI strings (measured keys) | Catalog rows | Dialogs / tooltips / help | Script support | Native review | Status | To full |

Other shipped languages
8 more, each at 1,608 / 1,608 measured keys, status partial for the same reason: Traditional
Chinese zh-hant (2,329 rows), Russian ru (2,544), Ukrainian uk (3,375), Czech cs (3,522),
Polish pl (3,366), Greek el (3,481), Dutch nl (3,568), Italian it (3,928; also every dynamic label the
other catalogs translate, notes). Turkish tr (3,731 rows) also covers every
measured key.
Czech UI follow-up (2026-10-11): status and notice wrappers, hardware labels, brush and
transform accessibility names, rasterization prompts, profile mismatch messages and preset
counts now translate at their render/assignment sites. Navigator's zoom level uses a context
(Zvětšení), while the tool remains Lupa. Engine errors, profile/file/document names stay
verbatim; copied System Info and control API diagnostics remain English while their on-screen
labels translate. Import warning counts use parentheses in Czech. New dynamic templates fall
back to English in catalogs without entries. This is additional UI coverage, not a claim that
engine localization or native review is complete.
Cross-language gaps
- Engine error, status and parameter-help messages are English in every language.
- Right-to-left UI layout is partial (2026-10-10): the shell mirrors for Arabic, Hebrew, Persian,
Urdu and other right-to-left codes (
direction.rs), but panel interiors, dialogs, menu rows, submenus and document tabs stay left to right. UI labels also lack an Arabic fallback font, and egui 0.36 joins letters within a word but orders a line's words left to right (no bidi). - Web build: no browser-locale detection, no CJK web fonts.
- WebAssembly plug-ins disappear from Filter › Plug-ins when the UI isn't English (#2540).
- A user couldn't find the language option (#2532): it is in Preferences › Interface.
