fixtounicode – Utility functions for setting tounicode mappings for 7/8 bit fonts

This package provides utility functions in expl3 and LaTeX2ε syntax for setting tounicode mappings for 7/8 bit fonts. The package provides a unified interface which enables mappings for both pdfTeX and LuaTeX.

The aim is to make it easier to make legacy (text) symbol packages, which often use arbitary glyph names and encodings, accessible for the two engines currently capable of producing accessible PDFs.

The package provides a limited workaround for LuaTeX 1.22 and earlier, which make the provision of such mappings more challenging.

Full support requires pdfTeX or LuaTeX 1.24 or later.
