fixtounicode

=================================================

Simple convenience wrappers designed to help in adding 'tounicode' values to Postscript type1 fonts installed as TeX fonts for use in LaTeX.

The package is primarily designed for use in type1 symbol font packages. So the main interface consists of a couple of expl3 functions. This can either be used directly or via a 2e command using key-value syntax.

In case document authors wish to add mappings for symbols which do not have them (perhaps to make the resulting PDFs accessible via screen- readers), a more convenient key supports setting Unicode values by glyph name. This is intended for use where an author needs to add mappings for a small number of symbols from a font, rather than mapping all symbols as a package would.

Compatibility

=================================================

pdfTeX | LuaTeX 1.24 or later

pdfTeX and recent LuaTeX (1.24 or later) are fully supported if output is direct to PDF.

LuaTeX 1.22 or earlier

LuaTeX 1.22 and earlier is partially supported, but the interface is more restricted and the addition of supplemental mappings depends on how 'nice' the encoding is.

For example, adforn, adfarrows and adfbullets exemplify ideal encodings: glyphs are assigned to slots starting from 0 with no gaps. Hence, these can be fully mapped.

Zapf Dingbats exemplifies a trickier case. The first used slot is not 0 and the encoding has multiple gaps. It is, therefore, possible to map any contiguous range of glyphs, but not all at the same time. (At least, it is not possible with this package.)

marvosym, however, I could not get to work at all with TL2025's unfixed LuaTeX.
