Hello Lauris!  Thank you so much for explaining gnome-print so well!  Your
explanation sure helps us understand and solve font problems.

I have a patch for you.  Some fonts have "-" in their fontname, but XLFD
does not allow this, so this patch converts all "-" to "_" in familyname.

Now, I also converted "&" to "+" because I ran into problems (or I thought I
ran into problems) a few months ago with fontnames containing "&" (not
gnome-print related).  However, I just checked XLFD.txt and noticed that "&"
is a valid field value, and can be legally used for familyname.  (oops!)
So, perhaps I was paranoid.  :-)  So, you may want to remove this line
after applying the patch:

        if (ttf->gfi.familyName[i] == '&') ttf->gfi.familyName[i] = '+';

XLFD.txt does mention this though:

  Field values are constructed as strings of ISO 8859-1 graphic charac-
  ters, excluding the following:

  o    "-" (HYPHEN), the XLFD font name delimiter character

  o    "?" (QUESTION MARK) and "*" (ASTERISK), the X protocol font name
       wildcard characters

  o    "," (COMMA), used by Xlib to separate XLFD font names in a font
       set.

  o    """ (QUOTATION MARK), used by some commercial products to quote a
       font name.

So, besides  - , you may want to convert  ? * , "  to   _   too.  :-)

Cheers,

Anthony
