📄 Description

The current TextBuffer implementation will happily overwrite the
leading/trailing half of a wide glyph with a narrow one without
padding the other half with whitespace. This could crash AtlasEngine
which aggressively guarded against such inconsistencies.

Closes #13522

Validation Steps Performed

  • Run .bat file linked in #13522
    (Override wide glyph with a single space.)
  • AtlasEngine doesn't crash ✅
