Re: postscript fonts vs. pango aliases

["Adrian E. Feiguin" <afeiguin uci edu>]

Clarification:
When I say that Standard Symbols L dont's display at all, I mean with  
libgnomeprint. In gtk, I get the text displayed with sans.
Dingbats do display with libgnomeprint, but not with gtk, and I get sans 
again
Othe fonts that do this are:

URW Gothic L Book  (as I mentioned before)
Nimbus Sans L Regular Condensed
