`cargo xtask assets` pins a SHA-256 for every catalog, so editing `es.tsv` left its ATTRIBUTION.toml entry stale and `assets::tests::the_real_manifest_passes` failed on both runners. Re-verified the file's provenance, updated the hash, recorded that the coverage additions are AI-assisted and not separately native-reviewed -- as #2510 did for `lt` and `vi` -- and regenerated ATTRIBUTION.md. Review notes on docs/localization-parity.md: - Lithuanian's `2,585 entries` was measured on 2026-10-13 and read as if `lt` were behind. Re-measured today it covers the whole 2,674-key union, so it is restated like `es` and `vi`. - *How this was measured* now says outright that the union is a moving target: every change that adds a string widens it, a count only compares with others of the same date, and a catalog at 100% falls behind without losing a translation. Earlier revisions quote the union of their own date, not this one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

|
||
|
||
Per-language status of PdfCraft's interface against Acrobat Pro's. How translations work and how to
|
||
add a language: [localization.md](localization.md). Summary in [ROADMAP.md](../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 as `theme`/`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 **2,674** keys as of 2026-10-20, 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 and Lithuanian, 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](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, but **release builds have no Hans face**: many characters show as boxes (#826, #688, #728, #758; Flatpak #689) | no | partial | yes | 6–12 |
|
||
| Spanish | `es` | 2,674 (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); no Devanagari face in craft-fonts | no | none | no | 10–18 |
|
||
| Arabic | `ar` | 2,143 (100%) | dialogs and tooltips; no help | Letters joined and lines reordered at load, but **layout not mirrored**, wrapped lines break at the wrong end, typed text runs left to right (`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` | 2,130 (99.4%) | 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` | 2,674 (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 (Hans face, RTL layout, 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.
|
||

**14 other languages** ship (22 catalogs plus English = **23** interface languages in Preferences).

The entry counts without percentages were measured on 2026-10-12–13; 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, Finnish, Norwegian, Swedish, Hebrew. Vietnamese is shipped here but not by Acrobat.

## Revision history
|
||
|
||
| Date | Change | Summary |
|
||
|---|---|---|
|
||
| 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 |
|
||
| 2026-10-13 | 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 |
|
||
| 2026-10-12 | 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 |
