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.
