pdf-font: unify best-effort fallback construction - #254
Merged
Conversation
Route every missing or unreadable font through one infallible TrueType fallback builder. Preserve valid widths, encoding, and ToUnicode data while treating malformed optional metadata as absent. Use the same fallback for Type0 font programs and ignore malformed CID mapping metadata so damaged resources remain renderable. Co-authored-by: Codex <codex@openai.com>
