fn base14_glyph_units(face: Base14Font, ch: char) -> f32Expand description
Width of a single character in a Base14 face, in 1/1000 em. WinAnsi
natives go through the baked O(1) table; extended glyphs (Latin
Extended-A, math operators, ligatures) go through the baked sorted
name index. Anything else (Cyrillic, CJK, emoji) silently returns
the width of ?; the PDF emit path renders those characters as
? too, so widths and content stream stay in sync. Embedded
families exist precisely so callers wanting real coverage can opt
out of this ?-everywhere behaviour.
