Add extraction for uni/u style glyphs - #721
Conversation
📝 WalkthroughWalkthroughThe font APIs add a strictness-aware ChangesFont Unicode Mapping
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Glyph-name extraction remains mergeable, but long names may be processed inefficiently because the full hexadecimal suffix is revalidated for every code-point group; the bounded performance risk should be addressed or explicitly accepted by the owner.

- Around line 172-176: Update the composite glyph handling in AdobeGlyphList to
return an empty result immediately when mapComponent(comp) yields an empty
string, rather than appending it and retaining previously mapped components;
preserve concatenation only when every component resolves successfully.
