Mapping from Unicode value to glyph index. Way seems to be via Unicode: most TrueType fonts provide a correct Glyph in TrueType fonts, rather than using names. If glyph names are not correct, we need a better way to refer to a If we encounterĪ font that does not have correct names for its glyphs, we need to do But, as explainedĪbove, glyph names in TrueType are not very reliable. Furthermore, most font tools rely on this convention andĪll encoding files (.enc files) use glyph names. So used to the Type 1 encoding convention, which relies on correct The potential problem with using TrueType in pdfTeX is that we are It is usually not a big deal and often goes unnoticed. So, if glyph names in a TrueType font are wrong or missing, As mentioned before, TrueType does not use names forĮncoding. If a glyph has a wrong name, it gets noticed The reason is that Type 1 fonts rely on correct names to One may wonder why things can be so complex with glyph names in the font contains correct names for most glyphs, and no names or wrong names for a few glyphs.Newer versions of Palatino fonts by Linotype (v1.40, coming with Windows XP) are examples of this. The font contains no glyph names at all.This is the worst situation that often happens with poor-quality fonts, or fonts converted from other formats.
