Hi,
I tried the suggested change to ~/.fonts.conf but am getting an error
from fontconfig:
$ fc-match symbol
Fontconfig error: "~/.fonts.conf", line 10: junk after document element
s050000l.pfb: "Standard Symbols L" "Regular"
$ cat ~/.fonts.conf
<match target="pattern">
<test name="family">
<string>Symbol</string>
</test>
<edit name="family" mode="prepend" binding="same">
<string>Standard Symbols L</string>
</edit>
</match>
<alias binding="same">
<family>ZapfDingbats</family>
<accept><family>Dingbats</family></accept>
</alias>
I have an alias in there to solve the "q" symbol being used in Evince
etc in place of pch == 1.
Am I inserting this incorrectly?
Many thanks,
G
