This package provides utility functions in expl3 and LaTeX2e
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.
