Well, a lot of toolkits uses fontconfig to dispatch font characteristics
to font file and some of them pango to substitute missing glyphs.
One could add a hook into fontconfig library. However I predict strong
opposition in upstream as fontconfig does not need X11 at all:
$ ldd /usr/lib64/libfontconfig.so
linux-vdso.so.1 => (0x00007fffa1784000)
libfreetype.so.6 => /usr/lib64/libfreetype.so.6 (0x00000035d7a00000)
libexpat.so.1 => /lib64/libexpat.so.1 (0x00000035d6a00000)
libc.so.6 => /lib64/libc.so.6 (0x00000035d0a00000)
/lib64/ld-linux-x86-64.so.2 (0x00000035d0600000)
Maybe some optional dbus code could be included to broadcast request for
missing font. If user had running an appropriate listener (some sort of
packagekit or font selector), he could get an systray alert or popup
window allowing to install missing package.
Other question is: should the hook block the application and retry
fontconfig font selection, or should it be completely asynchronous?
