* M14: add Norwegian Bokmål interface and date language A 2,592-entry `nb.tsv` covering every key the other bundled catalogs have, written from the meaning of the English labels (clean-room); terminology reviewed by a native-speaking contributor. Registers `nb` with the English one/other plural rule, adds Norwegian month and weekday names for Fill & Sign dates, resolves `no` and `nn` locales to Bokmål until a Nynorsk catalog exists, attributes the catalog and records it in parity. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * M14: translate the strings main added since the Norwegian catalog was written 69 keys (signature appearance labels, word count, full-screen prompt, print as image, image crop, redaction mark appearance, …) and the attribution hash. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * M14: translate the picture-menu and label-paper strings in the Norwegian catalog Seven keys main added (Cut/Redact Image, Create Link…, Recognize Text…, Turn upside down, the 4 x 6 in label paper) and the attribution hash. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * M14: translate the page-group folding commands in the Norwegian catalog Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * M14: drop the superseded localization summaries left beside the current ones Concurrent merges on main left older copies of several localization summaries next to their replacements. Review of #1836 flagged them: - localization-parity.md: remove the 2026-10-13 status line and the 14-language summary that still listed Norwegian as missing; the current summary keeps the Italian (and now Norwegian Bokmål) measurement dates. - localization.md: keep one catalog-coverage paragraph (now naming Norwegian Bokmål, up to about 2,700 entries) and one font paragraph. The font paragraph folds in what only the older copies said: the installed Chinese face fallback (#826) and Slovenian's Latin faces and four plural forms. - roadmap.md: end the M14 Missing list before the Fontconfig note.

Localization parity
Last reviewed: 2026-10-10 · Last updated: 2026-10-19 · Change: minor (superseded status line and language summary removed) · Target: Adobe Acrobat Pro (Acrobat DC, continuous track 26.002.21931, macOS)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 current denominator is the union of keys across all catalogs (2,590 plain keys as of 2026-10-13, plus language-specific context rows such as Vietnamesetheme/Appearance). The twelve-language percentage table below still quotes the historical 2,143-key snapshot from 2026-10-10 for every language except Vietnamese (re-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, 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 |
2,046 (95.5%) | 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 |
2,591 (100% of current union + theme Appearance) | 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. Vietnamese's To full hours are therefore residual help/docs polish
(catalog and script work are already done), not missing UI strings.

15 other languages ship (23 catalogs plus English = 24 interface languages in Preferences). The entry counts without percentages were measured on 2026-10-12–13 (Italian on 2026-10-14, Norwegian Bokmål on 2026-10-18); 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, Swedish, Hebrew. Vietnamese is shipped here but not by Acrobat.
