The stub returned nil and left the language output untouched. Chromium pre-fills that output with a sentinel and reads it whenever it is non-NULL, so the League client UI read garbage. Return CTFontCopyName and always write NULL to the language output. The CoreText font-list check now covers both. Co-Authored-By: Claude Opus 5.5 <[email protected]>
