Original Pull Request: https://github.com/microsoft/terminal/pull/12307

State: closed
Merged: Yes

IDWriteTextAnalyzer::GetGlyphs is not enough to get a
DWRITE_SHAPING_TEXT_PROPERTIES::canBreakShapingAfter
value that works for combining diacritical marks.
This requires an additional call to GetGlyphPlacements.
This commit increases CPU usage for complex text by ~10%.

PR Checklist

Validation Steps Performed

  • echo "[e`u{0301}`u{0301}]" prints an "e" with 2 accents ✅
