Summary

Fixes to editing Korean text on slides.

• Fonts named in Korean are found. Decks made on Korean systems name fonts like "맑은 고딕" or "나눔고딕". The font catalog now keeps each family's names in other languages. FontDb::canonical maps them back to the family, so those runs no longer fall back to another face.
• The Font box sets the East Asian font for East Asian fonts. format.font used to set only the Latin font, so picking a Korean font left the Hangul unchanged. When the chosen family's own face has Hangul, kana or CJK ideographs, the run's font_ea is set too. A stand-in face for a missing family never counts. A Latin-only font still changes only the Latin font.
• Korean words, not syllables. Hangul counted as an ideograph, so Ctrl+arrow, Ctrl+Backspace/Delete and double-click worked one syllable at a time, and Ctrl+B inside a word didn't bold it. Korean separates words with spaces, so Hangul is now a word character. Line wrapping already treated it that way.
• Spelling. Typed Hangul usually carries the deck's English language tag, so an installed English dictionary flagged every Korean word. Hangul words are now checked as ko-KR:
  • They are skipped unless a Korean dictionary is installed.
  • A run counts as Korean by its primary language subtag, so kok (Konkani) is not Korean.
  • Hangul written next to other letters ("PPT발표") is checked separately from them.
• Shaping and line breaking.
  • Hangul shapes with language ko and kana with ja, so fonts pick their local forms.
  • Hangul Jamo Extended-B and halfwidth Hangul (U+FFA0–FFDC) count as Hangul.
  • Line breaking now uses the same Hangul check, so a halfwidth Korean word isn't split.

Hanja conversion (the Hanja key during composition) already works through the IME; it was checked by hand with the Windows 11 Korean IME (한 → 韓).

Scope change

This PR first also fixed an IME bug. A click or command while a syllable was composing settled it in the slide but not in the system IME, which doubled it: 안녕, click, 나 gave 안녕녕나.

main now handles this in the egui 0.37 migration (#1350), with the settled-composition interrupt and tombstone in ui-egui. So that part was dropped when rebasing, and this PR now changes no IME code.

Tests

• fontdb::font_dir_tests::installed_fonts_are_found_by_their_korean_names: uses NanumGothic from craft-fonts; skipped without it.
• tests::a_korean_font_is_the_east_asian_font_too: needs NanumGothic and a Latin-only font that is installed or bundled.
• spell::tests::hangul_words_are_korean: covers the kok-IN and "PPT발표" cases.
• words and ctrl_arrows_over_cjk_rtl_emoji_and_marks are updated: 한국어 문장 is two words.

Validation on Windows after rebasing on aaf6c1c3:

• passed: cargo fmt --check, cargo clippy -D warnings (model, fonts, text, engine, ui-egui)
• cargo test --lib for model, fonts, text, engine and ui-egui: all pass

The branch is one commit per feature (font names, East Asian font slot, word boundaries and ko shaping, spelling) plus a docs commit; each builds on its own. Local results on macOS at 8125a686 are in the latest comment.

Not covered:

• macOS ([ MacOS 15.8.1 Intel ] Cannot type Chinese or Korean and crash when closing it. #710)
• altLang round trip
• eaLnBrk

Related to #101.

Overlap with main

Checked against current main (9005839). main already wraps Korean at spaces (#276); this PR only shares that check (deckcraft_model::words::is_hangul) and extends it to halfwidth Hangul. The IME fix was dropped earlier because #1350 covers it. Everything else (Korean font names, East Asian font from the Font box and Font dialog, Hangul word boundaries, ko/ja shaping language, Korean spelling) is not in main.

Summary by CodeRabbit

• New Features
  • Korean text is now recognized as word-based content, enabling more natural word selection, Ctrl+arrow navigation, and deletion.
  • Korean-named fonts can be found and selected. Choosing a Korean font also applies it to East Asian text.
  • Korean words are no longer flagged by English spell-checking, and Hangul text uses Korean shaping.
• Documentation
  • Updated Korean editing guidance and localization notes.

Walkthrough

This change adds Korean-aware Hangul classification, word and spelling behavior, shaping language defaults, localized font-name lookup, and East Asian font assignment when selecting qualifying fonts.

Changes: Korean Editing

Layer / File(s)	Summary
Hangul text handling crates/model/src/words.rs, crates/fonts/src/script.rs, crates/text/src/breaking.rs	Hangul and jamo now use a shared character classification and are excluded from ideograph tokenization. Hangul receives the Korean shaping language default, and text wrapping uses the shared classification. The tokenization test groups Korean text into space-separated words.
Localized font discovery and assignment crates/fonts/src/fontdb.rs, crates/engine/src/cmd/format/font.rs, crates/engine/src/tests.rs	Font scans collect localized family names and resolve aliases to canonical names. Selecting an installed Regular face with Hangul, kana, or CJK coverage also sets the East Asian font. Tests cover Korean-name lookup and font selection.
Korean word editing and spelling crates/engine/src/spell.rs, crates/engine/src/tests_keys.rs, docs/localization-parity.md, ROADMAP.md	Word segmentation separates Hangul from adjacent text and assigns ko-KR when the run language is not Korean. Tests cover language assignment, spelling, and Ctrl+arrow navigation. The documentation and progress log describe the Korean editing changes.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Suggested reviewers: dylanmtaylor, echelon

Merge Risk: Low · previous review 89548

Localized font names may not list available styles. The change is mergeable with that limitation understood.

Security architecture risk: Low · up to 89548

On desktop, a rejected font addition can still affect font choices in other documents opened in the same application. The established impact concerns document appearance; no broader data access or privilege increase was identified.

Retained concerns

• Low · architecture · inferred: Native font additions can commit process-wide localized aliases despite reporting failure. add_fonts extracts and merges aliases before determining how many faces were inserted; font.add rejects a zero-face result. A redundant font carrying new localized names can therefore influence later documents' font resolution without a successful registration result. Global face registration already existed, but this PR introduces the independently committed alias state. The supported concern is shared-state ownership and failure containment, limited by existing-family precedence; a security-sensitive downstream outcome has not been established.

Security review details

Security Blast Radius

• inferred — Embedded fonts and font.add both feed the process-global database. New localized mappings can consequently influence another document using that database, including later missing-font checks and rendering lookup. The established scope is native documents sharing one process, not other processes, tenants, machines, or services. Process-global face registration itself predates this PR.

Security Findings and Attack Paths

• inferred — A caller able to submit font bytes can supply new localized names on an otherwise duplicate family and style. Alias extraction occurs before duplicate-face rejection, so the command can return an error while retaining those names for subsequent resolution. This supports the ownership concern above, but does not establish execution, disclosure, or authorization bypass.

Trust Boundaries and Controls

• observed — Existing loaded or cataloged family identities bypass alias substitution, and alias insertion does not overwrite existing mappings. East Asian formatting additionally checks the returned face's family identity and coverage, preventing a missing family's fallback face from qualifying it.

Resilience and Maintainability Implications

• observed — First catalog initialization waits for scanning and alias merging to finish. This prevents the proposed fresh-database first-lookup race; it does not make later alias publication and face insertion one transaction.

Use a controlled Latin-only fixture for the font-coverage assertion.

If Lato is unavailable, is_east_asian_font returns false, while format.font still stores "Lato". The test can therefore pass without exercising the Latin-only branch. This is an incomplete regression-coverage improvement, not a broken test workflow.

FALLBACK_FAMILY is not guaranteed to be available or Latin-only. Guard its availability and assert its coverage before using it.

Check aliases before scanning the catalog.

canonical performs a linear catalog search for each not-yet-loaded family before checking aliases. Rendering and text paths call document_face and has_family repeatedly, so unknown or localized names can repeat this scan. Loaded families skip the branch, and iter().any(...) can stop at an earlier match.

Check the alias map first. Check catalog membership only when an alias exists to preserve canonical-name precedence. This reduces scans for non-alias names; localized aliases still require the catalog check.

🟡 Minor · Include halfwidth Hangul in the line-break Hangul predicate. · script.rs:88-89

crates/fonts/src/script.rs:88-89
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Include halfwidth Hangul in the line-break Hangul predicate.

When adjacent U+FFA0–U+FFDC characters wrap, unicode_linebreak::linebreaks can allow a break between them because Unicode classifies them as ID. break_opportunities does not remove that break because is_hangul excludes the range. break_lines can then use it as last_break and split a halfwidth Hangul word. Add the range to this predicate.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Defer consuming ime_interrupt until an IME output exists.

A canvas click ends composition before ime_output runs. A click on empty canvas clears the selection, so ime_area returns None. The current code consumes ime_interrupt before that return and emits no IMEOutput. The native IME is not told to stop, so its next keystroke can grow the settled syllable at the new insertion point.

Move the take after the guards:

     // A click on the canvas this frame may have settled a composition.
     app.settle_ime();
-    let settled = std::mem::take(&mut app.ime_interrupt);

Clear a pending IME interrupt when a new composition starts.

A non-canvas frame can leave ime_interrupt set after settlement. A later nonempty IME event clears only ime_settled, so canvas output can pass the old interrupt to the newer composition through should_interrupt_composition. The newer composition can then be interrupted and lose uncommitted text. Preserve the matching late-commit return, but clear ime_interrupt for other nonempty IME events.

@coderabbitai Addressed the three outside-diff findings in 2ccae77:

• Halfwidth Hangul line breaking: crates/text now uses deckcraft_model::words::is_hangul, which includes U+FFA0–FFDC, so a halfwidth Korean word isn't split.
• ime_interrupt is taken only after ime_area returns an area, i.e. when an IMEOutput carries it. With no output egui-winit turns the input method off, which ends the composition anyway.
• A non-empty preedit or a commit clears a pending ime_interrupt, so it can't interrupt a later composition.

@BBQ-MAN Thanks. I inspected 2ccae77. The changes address the three findings:

• Line breaking now uses the shared is_hangul helper, which includes U+FFA0–FFDC.
• ime_output takes ime_interrupt only after the output guards pass and ime_area returns an area.
• A non-empty preedit or a normally handled commit clears the pending interrupt before further event handling.

This was source inspection only. I did not run tests or verify platform IME behavior.

Rebased onto current main (f893f6a) as 895484f0:

• main split cmd/format.rs and crates/text/src/lib.rs into modules. The East Asian font change is now in cmd/format/font.rs, and the halfwidth-Hangul line-break check (deckcraft_model::words::is_hangul) is in crates/text/src/breaking.rs.
• Addressed the three CodeRabbit findings in 895484f (replied inline):
  • The Font dialog sets the East Asian font for an East Asian family, as the Font box does (set_family).
  • Bundled fonts and fonts added with font.add are found by their Korean names too.
  • The spelling test no longer assumes no Korean dictionary is installed.
• Checked the PR against main for anything it now does itself: nothing to drop. Korean line wrapping was already main's (Text: wrap URLs, Korean and CJK punctuation where PowerPoint does #276) and this PR just reuses that check; the IME part went earlier with Migrate DeckCraft to egui 0.37 #1350.

Validation on macOS, with craft-fonts:

• passed: cargo fmt --check, cargo clippy -D warnings (model, fonts, text, engine), cargo xtask layers, cargo xtask assets, cargo xtask wasm
• cargo test for model, fonts, text and engine: all pass (702)

Resolve localized names in styles.

If has_family("나눔고딕") resolves to NanumGothic, styles("나눔고딕") still returns an empty list. styles compares the Korean name directly with the stored English family name. Canonicalize family before both style searches so clients can list styles for a font they can select.

Update FontDatabase::styles to canonicalize the requested family name before
both style searches, reusing the same resolution behavior as has_family so
localized names such as “나눔고딕” return styles for the resolved family.

ReviewerA — source-read COMMENT (not an approval)

I read the head of the diff: Korean editing (#101). Fonts named in Korean (맑은 고딕, 나눔고딕) are found, picking a Korean font sets the East Asian font as well as the Latin one (set_family(r, &f, ea) with is_east_asian_font), and the ROADMAP also lists word boundaries and spelling. PowerPoint sets the East Asian typeface when a font that belongs to an East Asian script is chosen, so picking 맑은 고딕 changes the Korean text and not only the Latin letters around it. That follows ECMA-376's font slots and is related to deckcraft#1049 (Latin-slot neutrals). Four features in one PR (font names, font slots, word boundaries and spelling) are hard to review, and Korean word segmentation and spelling data need provenance; the spelling dictionary's licence is the question. I read the font part. I have not run it, and no exact-head CI result exists for this head. Nothing was run.

I ran nothing and have no exact-head CI result for this PR, so this is not an approval. Where a diff was long I read its code hunks rather than every generated or documentation line.

Status: waiting_author.

Rebased onto current main (9005839) as 8125a686. Only the ROADMAP log and the localization-parity header conflicted; no code changes from the rebase.

@FredApps, thanks for reading it. On your points:

• Four features in one PR: the branch is now one commit per feature, and each builds on its own:

  • dec8b594 Korean font names
  • 8aa02df0 East Asian font slot
  • 3a0b646b word boundaries and ko shaping
  • d78d19ed spelling
  • 8125a686 docs

  Happy to split them into separate stacked PRs if that's easier.

• Font slots / Text: Latin-slot neutrals, centipoint advances, metafile symbol fallback #1049: choosing a font whose own face has Hangul, kana or CJK sets both latin and ea (Font box and Font dialog); a Latin-only font sets latin only. That fits Text: Latin-slot neutrals, centipoint advances, metafile symbol fallback #1049's rule that neutrals use the Latin slot: after picking 맑은 고딕 the Latin slot is 맑은 고딕 too. The two PRs share only fonts/src/script.rs, in different places.

• Segmentation provenance: there's no segmentation data. Hangul is a word character by Unicode block (words::is_hangul), and Korean separates words with spaces.

• Dictionary licence: no dictionary is shipped or downloaded. Hangul words are checked as ko-KR with main's existing Hunspell lookup, so only a Korean dictionary the user installed is used; without one they're skipped instead of being flagged by the English dictionary.

Local validation on macOS at 8125a686, with craft-fonts:

• passed: cargo fmt --check, cargo clippy -D warnings (model, fonts, text, engine), cargo xtask layers, cargo xtask assets, cargo xtask wasm
• cargo test for model, fonts, text and engine: 764 passed, 0 failed
