Add ligature codepoints (U+FB00–FB06) to font conversion so all fonts include ligature glyphs. Implement utf8NextCodepointWithLigatures() that does lookahead substitution for f-ligature sequences. Use it in text rendering and measurement so ligatures render correctly and word-wrapping accounts for the ligature glyph widths.
