The chat "Emoji style: Color" option renders the merged emoji in color (COLR/CPAL
Twemoji) instead of the monochrome NotoEmoji subset. This needs FreeType, which the
default stb_truetype rasterizer can't do for color glyphs.
- Vendor imgui_freetype (matches the bundled 1.92 ImFontLoader API) and embed a 1.4 MB
COLRv0 Twemoji font (no libpng/harfbuzz needed).
- CMake gains an optional FreeType path: native Linux/macOS use the system FreeType via
find_package; the mingw-w64 cross-compile has none, so build.sh --win-release now
cross-builds a minimal static FreeType (scripts/build-freetype-mingw.sh) and passes it
in. Absent FreeType => graceful monochrome fallback, so no build breaks.
- Typography selects the FreeType loader + the color font (LoadColor) when color emoji is
on, else the stb loader + mono subset; toggling reloads the atlas. Both the DX11 and
OpenGL backends already support the 1.92 RGBA dynamic atlas, so color glyphs render.

Merge a monochrome Noto Emoji subset into the text fonts so chat messages, the
composer, contact names, and memos render emoji (😀🎉 ❤ 🔥👍 …) instead of
tofu.
- Enable IMGUI_USE_WCHAR32 (imconfig.h): emoji live above the BMP (U+1F300+), so
16-bit ImWchar literally can't address them. This widens ImWchar build-wide;
the only ImWchar uses in-tree are glyph-range arrays and one BMP private-use
codepoint, so nothing else is affected. Tests + full build pass.
- Bundle res/fonts/NotoEmoji-Subset.ttf — the OFL monochrome Noto Emoji (color
CBDT/COLR fonts can't be rasterized by ImGui's stb_truetype) pinned to wght=400
and subset to the emoji planes (1411 glyphs, 747 KB). Reproducible via
scripts/build_emoji_subset.py. Embedded via INCBIN like the CJK subset.
- Typography::loadFont merges it (MergeMode) only into the small text fonts
(Body/Subtitle/Caption/Button) — not headers, which don't need 1400 emoji.
The base font keeps precedence for U+2600–26FF, so text-style symbols stay.
Limits: ImGui does no shaping, so single-codepoint emoji render but ZWJ sequences
(family/profession) and regional-indicator flags won't compose; emoji are
monochrome (the OS emoji picker still inputs them fine, and the composer byte
counter already counts their 4-byte UTF-8 cost against the on-chain cap).
Verified headless: sizeof(ImWchar)==4 and every probed emoji is in-font and bakes
into the atlas.
