CTAN update: LuaTeX-CN
by CTAN Announcements 09 Aug '26

09 Aug '26

Frank Lin submitted an update to the LuaTeX-CN bundle. Version: 0.4.1 License: apache2 Summary description: A LuaTeX based package to handle Chinese text typesetting Announcement text: ------------------------------------------------------------------------ luatex-cn 0.4.1 -- first update on CTAN since 0.3.1. luatex-cn typesets Chinese with LuaLaTeX in both writing directions: faithful reproduction of classical (guji) page layouts, and modern Chinese typesetting following the W3C Requirements for Chinese Text Layout (clreq). Highlights since 0.3.1: * Unified entry point: \usepackage{luatex-cn} now loads the new horizontal clreq pipeline by default (options are passed through, e.g. [style=taiwan]); the [vertical] option or any ltc-* document class selects the vertical engine, with 0.3.x semantics unchanged. * Horizontal clreq pipeline (new): CJK-Western spacing (1/4 em, compressible to 1/8, stretchable to 1/2, with the exceptions clreq specifies), punctuation width adjustment with Mainland China / Taiwan / untouched presets, quote-style conversion, four-level line-breaking prohibitions and non-separation rules, intra-line compression/stretching in clreq priority order, half-width punctuation at line end, hanging punctuation, interlinear marks (proper-name mark, book-title mark, emphasis dots), word-aligned pinyin ruby, paragraph/page controls (orphan handling, hanging indentation, last-line alignment). * Vertical clreq conformance: 1/4 em CJK-Western boundary spacing, \Sideways (rotated Western text), \CombineUpright (tate-chu-yoko), hanging punctuation at column end, clreq-conformant emphasis dots per document class. * A shared rules kernel used by both directions (single source for the clreq punctuation table, space-distribution solver and prohibition rules), a published conformance matrix (doc/CLREQ-CONFORMANCE.md), and 119 PDF-content-stream metric assertions run in CI. * Installation-free fonts: \setmainfont with a bare font file name, registry aliases, and a helper script that installs fonts into TEXMFHOME without touching the system font library. * Typesetting additions from the 0.3.x series: tables with cross-page support and horizontal bands, European-style genealogy charts, gongche (traditional musical notation), illustration pages, colophon (paiji) boxes, multi-level headings, and a modern vertical book layout in the style of Zhonghua Shuju (footnotes, first-line indentation, alternating running heads). * 0.4.1 fixes: Western words in annotations/textboxes are no longer hyphenated and mis-columned; in fixed-grid mode \Sideways now sizes rotated words by their advance width.

CTAN update: xecjk
by CTAN Announcements via ctan-ann 09 Aug '26

09 Aug '26

Liam Huang submitted an update to the xecjk package. Version: 3.10.5 License: lppl1.3c Summary description: Typeset CJK in XeLaTeX Announcement text: -------------------------------------------------------------------------------- This release fixes several bugs related to CJK glue handling, brace-group consumption, hyperlink anchors, and underline/strikethrough decorations, and adds a new transparent wrapper variant for brace-delimited argument forwarding. BUG FIXES - `\CJKecglue` inserted at source-space positions now uses a portable code path, preventing its shrink component from being frozen inside the fixed-width segment boxes produced by `ulem` (#1037). - Before boundary detection, category-code-4 `&` in the parameter copy is replaced with `\scan_stop:`, fixing compilation errors when commands like `\colorbox` receive arguments containing `&` inside `\halign` (#1043). - `\sbox` now uses a dedicated adapter: prefixes such as `\global` must immediately precede `\setbox`, but assignments placed in the `cmd/sbox/before` hook consumed the prefix, causing `\global\sbox` to silently degrade to a local assignment (#1029). - Only the single triggering left brace is now absorbed instead of swallowing the entire group and re-emitting it, fixing the `Improper alphabetic constant` error when `中文¥¥` appears in `tabular` (#1038). - Inline anchor outputs `¥hyper@anchor`, `¥Hy@raisedlink`, and `¥__hyp_target_raise:n` are registered as transparent captures so that `¥hypertarget`, `¥phantomsection`, `¥MakeLinkTarget`, unnumbered heading anchors, and manually wrapped anchors no longer mask the actual boundaries on either side; the path via `¥hyper@anchorstart` (e.g. `¥pdfbookmark`) is not yet covered (#1047). - The stream capture for `l3doc` is moved from the internal `¥__codedoc_meta:n` up to the public `¥meta`, so that `¥CJKecglue` on both sides is evaluated using the font metrics outside the command (#1046). - Period-style decorations now save end-of-segment state per nesting level, preventing an inner command from overwriting the right end of an outer one (#1012). - Body text now always enters `ulem` arguments as literal tokens: only "math followed by a trailing source space" is reformatted, and reformatting first assembles then expands once, preventing `¥CJKecglue` to the right of Latin words from being trapped in a fixed-width decoration segment box and losing its shrink component (#1026). - The user manual now explains that a nested segment inside line-style commands cannot break across lines, distinguishes line-style from symbol-style commands, and provides alternative approaches; a regression guard for the `¥UL@onin` path is added using "ability to line-break" as the observable (#1057). - Wavy underlines and diagonal strikethroughs now use a quarter-em drawing unit that scales with font size and ordinary `¥leaders`; the minus-sign variant insets by half a period at each end to prevent adjacent commands from merging (#1012). - Decoration content is wrapped in an empty `ActualText` marker, and LaTeX tagging is suspended during decoration box construction, preventing glyphs used by wavy underlines and diagonal strikethroughs from appearing in PDF text extraction results (#1017). NEW FEATURES - A new transparent wrapper variant is added that forwards arguments delimited by braces, for use by target functions that consume their argument as `¥hbox:n` content (#1047).
