With pdftex it is possible to restrict a \pdfglyphtounicode declaration to a specific tfm. So in the following example the A from cmr10 is mapped to B, but the A from cmss10 is untouched: \pdfgentounicode=1 \pdfglyphtounicode{tfm:cmr10/A}{0042} A \font\test=cmss10 \test A \bye This is useful, e.g., to setup unicode mappings for older symbol fonts which often (mis)use standard glyph names. With luatex this doesn't work. Only the "general" mapping is honored here: \pdfvariable gentounicode =1 \pdfextension glyphtounicode {C}{0044} \pdfextension glyphtounicode {tfm:cmr10/A}{0042} C A \font\test=cmss10 \test C A \bye Would it be possible to extend luatex to support the tfm: syntax too? Or is there an alternative to change tounicode mappings? -- Ulrike Fischer http://www.troubleshooting-tex.de/
