[tex-live] Fontconfig for XeTeX versus regular fontconfig

[Dr. Werner Fink]

Hi,

with several bug reports here I've the final problem that the
fontconfig setup used for XeTeX does not work well with all
other fontconfig.

With fontconfig setup for XeTeX, e.g. by using a

  /etc/fonts/conf.d/09-texlive.conf

there are reports of e.g.:

  ** ERROR ** Invalid glyph index (gid 2447)

and also reports of a slowdown of e.g. programs like Inkscape.

On the other hand users of XeTeX seems to rely on an
enabled fontconfig for XeTeX.

Is there a solution or a simple way to disentangle the usage
of fontconfig for both the non-XeTeX and the XeTeX users on
the *same* system.

E.g. it would help a lot if Xe(La)TeX and xdvipdfmx would
use the path mentioned in texmf.cnf (FC_CACHEDIR, FONTCONFIG_FILE,
and FONTCONFIG_FILE) instead of /etc/fonts/conf.d/09-texlive.conf
