A PDF whose fonts aren't embedded is drawn with PDFium's Foxit stand-ins for the standard 14 fonts. Those carry only the 230-odd glyphs of the Standard, WinAnsi and Mac Roman encodings, so a letter a font names beyond them in its /Differences mapped to .notdef and drew nothing. iText 2 writes Turkish exactly this way (Times New Roman left unembedded, /Gbreve /Idotaccent /Scedilla /gbreve /scedilla over Ð Ý Þ ð þ), and such letters showed blanks for Ğ, İ, Ş, ğ and ş while ı, ç, ö and ü drew. StandardKind now builds a Latin Extended-A letter the stand-in lacks from the base letter and accent it does have, as Type 1 seac composites and the standard-14 AFM composites are built: the accent is centred on the letter, raised over capitals and letters with ascenders (and moved along the slant in italics), cedillas hang below and ogoneks from the right edge. Composite glyph ids sit above any font's glyph count, one per character code; their width comes from the standard metrics of the name. Test: raster::tests::accented_letters_the_standard_stand_ins_lack_are_built_from_their_parts (fails without the patch: Gbreve drew no pixel). Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
