Localization parity
Last reviewed: 2026-10-25 · Last updated: 2026-10-25 · Change: minor (Persian (
fa, 2,785 entries) added right-to-left like Arabic and Kurdish; Arabic current state corrected: catalogs stay logical, RTL labels take an explicit direction and stock chrome mirrors; native/browser RTL input, IME and complex workflows remain unqualified. Native release Hans face via LXGW WenKai Lite; release-pinned craft-fonts still has no Telugu face. Current union 2,798 keys. Scores and estimates unchanged) · Target: Adobe Acrobat Pro (Acrobat DC, continuous track 26.002.21931, macOS)
Per-language status of PdfCraft's interface against Acrobat Pro's. How translations work and how to add a language: localization.md. Summary in ROADMAP.md.
How this was measured
- Strings translated is measured: the catalogs in
crates/ui-egui/src/i18n/<code>.tsv, counted as distinct(context, English)keys with a non-empty translation. The denominator is the union of keys across all catalogs, counting language-specific context rows such astheme/Appearance. That union is a moving target: every change that adds a string widens it, so a count is only comparable with others measured on the same date, and a catalog that reached 100% falls behind without losing a single translation. Every figure here therefore carries its date. The current union is 2,798 keys as of 2026-10-25, against the 2,143-key snapshot of 2026-10-10; earlier revisions quote the union of their own date (see the revision history), not this one. The twelve-language percentage table below still quotes the 2026-10-10 snapshot for every language except Spanish, Vietnamese, Lithuanian and Brazilian Portuguese, which are measured against the current union. English is built in. - Not counted: error details from the engine and the operating system, which are shown in English inside a translated frame; there is no translated user documentation or help yet (Acrobat ships localized help).
- Script support comes from localization.md, the vendored winit IME patches
(
vendor/README.md) and user reports. - Native review: "community" means a native speaker contributed or corrected the catalog in a pull request or issue; "no" means no record of review. No catalog has had a formal review.
- Acrobat ships 24 interface localizations on macOS (
.lproj: cs, da, de, en, es, fi, fr, hu, it, ja, ko, nl, no, pl, pt, ru, sv, tr, uk, zh_CN, zh_TW, plus en_AE, en_IL, fr_MA) and Middle East / North Africa editions (MEA Arabic, MEH Hebrew, NAF French;Resources/Sequences/).
The twelve key languages
| Language | Code | UI strings translated | Dialogs / tooltips / help | Script support | Native review | Status | Acrobat ships it | To full (h) |
|---|---|---|---|---|---|---|---|---|
| English | en |
built in (100%) | all; README and docs | Latin | yes | full | yes | 0 |
| Simplified Chinese | zh-hans |
2,088 (97.4%) | dialogs and tooltips through tl!; no help |
CJK text and IME work; native craft-fonts builds embed the LXGW WenKai Lite Hans face, while the web build has no Hans face beyond BIZ UDPGothic, and missing-glyph reports (#826, #688, #728, #758; Flatpak #689) predate the native face | no | partial | yes | 6–12 |
| Spanish | es |
2,798 (100% of current key union) | dialogs and tooltips; no help | Latin | no | partial | yes | 2–4 |
| Hindi | hi |
0 | none | Devanagari not tested (egui shapes Telugu conjuncts, so shaping is likely workable); the pinned craft-fonts manifest has Noto Sans Devanagari Regular; rendering remains unqualified | no | none | no | 10–18 |
| Arabic | ar |
2,143 (100%) | dialogs and tooltips; no help | Logical-order catalog; egui 0.37's epaint reorders with UAX #9, Arabic, Kurdish and Persian labels use an explicit right-to-left paragraph direction, and stock chrome is mirrored. Native/browser RTL input and IME, and complex bidirectional workflows, are not yet qualified (localization.md §Arabic) |
no | partial | yes (Middle East edition) | 25–45 |
| French | fr |
2,128 (99.3%) | dialogs and tooltips; no help | Latin | no | partial | yes | 1–2 |
| Portuguese (Brazil) | pt-br |
2,798 (100% of current union) | dialogs and tooltips; no help | Latin | community (#288) | partial | yes | 1–2 |
| Indonesian | id |
0 | none | Latin | no | none | no | 3–5 |
| Japanese | ja |
2,123 (99.1%) | dialogs and tooltips; no help | BIZ UDPGothic from craft-fonts; IME patched on macOS, Windows, X11, Wayland; vertical text renders but can't be edited | no | partial | yes | 4–8 |
| German | de |
2,128 (99.3%) | dialogs and tooltips; no help | Latin | community, in progress (#828: terminology, clipping) | partial | yes | 2–4 |
| Korean | ko |
0 | none | Hangul IME patched (Microsoft and Apple Korean, vendor/README.md winit 3, 6, 9, 10); no Hangul UI face in craft-fonts |
no | none | yes | 6–10 |
| Vietnamese | vi |
2,798 (100% of current key union) | dialogs and tooltips; no help | Latin with stacked diacritics; bundled Inter covers them (fonts test) | community | partial | no | 2–4 |
Localization dimension ≈ 68%: the mean over the twelve, counting a catalog's percentage but only
60% for Chinese and Arabic until their script problems are fixed, and 0 for Hindi, Indonesian and
Korean (still missing). Vietnamese moved from 0% to 100% in that mean (59% → 68%). ≈ 55–110 h
to bring all twelve to full, of which ≈ 35–60 h is engineering (remaining RTL qualification, a web Hans face, bidi text)
and the rest catalogs and fixes; native-speaker review needs humans.
No language is full except English: every catalog leaves engine error details in English, and
none has translated help. The To full hours of Vietnamese and Spanish are therefore residual
help/docs polish (catalog and script work are already done), not missing UI strings.

20 other languages ship (34 catalogs plus English = 35 interface languages in Preferences). The entry counts without percentages are as of 2026-10-25; they are not percentages of the older 2,143-key snapshot above. Their presence does not imply a detailed linguistic or runtime review. Acrobat languages PdfCraft lacks: Danish, Dutch, Swedish, Hebrew. Vietnamese is shipped here but not by Acrobat.
Revision history
| Date | Change | Summary |
|---|---|---|
| 2026-10-25 | minor | Arabic current state corrected: catalogs stay logical, Arabic/Kurdish labels take an explicit RTL direction, and stock chrome mirrors; native/browser RTL input, IME and complex workflows remain unqualified. Native Simplified Chinese uses LXGW WenKai Lite; the web build still has no Hans face and the release-pinned craft-fonts still has no Telugu face. Scores and estimates unchanged |
| 2026-10-25 | minor | Added Persian (fa, 2,785 entries, all but 13 of the current 2,798-key union); right-to-left like Arabic and Kurdish, with logical entries reordered by egui 0.37's epaint; AI-assisted, not yet native-reviewed |
| 2026-10-21 | minor | Brazilian Portuguese (pt-br) now covers all 2,674 distinct keys in the current catalog union; no help or engine/OS error-detail localization; twelve-language mean still rounds to ≈ 68% |
| 2026-10-20 | minor | Spanish: the 143 keys the other catalogs had and es.tsv was missing; es now covers the whole 2,674-key union, like lt and vi. Restated Lithuanian against the current union (its 2,585 was measured on 2026-10-13) and said plainly in How this was measured that the union moves, so counts only compare within a date |
| 2026-10-19 | minor | Removed the 2026-10-13 status line and the 14-language summary that concurrent merges left beside the current ones; the summary keeps the Italian and Norwegian Bokmål measurement dates |
| 2026-10-16 | minor | Czech: 2,674 entries after adding the keys the other catalogs had (the engine's sentences, weekday heads, certificate fields, shared buttons) and unifying "tag" as tag (not značka, which is a redaction mark) |
| 2026-10-13 | minor | Vietnamese (vi) catalog: 2,591 entries (100% of current key union + theme/Appearance); twelve-language mean ≈ 68%; native-speaker community review; registered with plural_none |
| 2026-10-14 | minor | Italian: 2,528 entries after adding the 201 keys the other catalogs had and the code looks up |
| 2026-10-14 | minor | Added Finnish (2,674 entries, AI-assisted) |
| 2026-10-12 | minor | Added Albanian (sq): catalog, date names, Preferences entry |
| 2026-10-14 | minor | Added Catalan (ca, 2,592 entries, measured 2026-10-14); retained existing language assessments |
| 2026-10-15 | minor | Romanian (ro) catalog: 2,673 entries (every bundled key); three plural forms (plural_ro); not one of the twelve key languages, so the mean is unchanged |
| 2026-10-15 | minor | Norwegian Bokmål added as an interface and date language with a 2,674-entry catalog |
| 2026-10-12 | minor | Added current counts for Kazakh, Polish, Slovenian, Greek, Turkish and Lithuanian; retained existing language assessments and the original percentage snapshot |
| 2026-10-10 | major | Created. Catalog counts measured from crates/ui-egui/src/i18n/*.tsv against the 2,143-key union; Acrobat's localizations from its bundle's .lproj and Sequences folder names |
