Installation

This package is meant to be installed automatically by TeXLive, MikTeX, etc. Otherwise, XCharter-Math can be installed under TEXMFHOME or TEXMFLOCAL, f.i. XCharter-Math.otf in directory texmf-local/fonts/opentype/public/xcharter-math/ and fourier-otf.sty in directory texmf-local/tex/latex/xcharter-math/. Documentation files and their sources can go to directory texmf-local/doc/fonts/public/xcharter-math/

Don't forget to rebuild the file database (mktexlsr or so) if you install under TEXMFLOCAL.

Finally, make the system font database aware of the XCharter Math font (fontconfig under Linux).
