The goose OpenType eggs holds...

["Vasile Gaburici" <vgaburici gmail com>]

I've found CFF OpenType versions of the ghostscript URW fonts. AFAICT,
they are well done: have kerning pairs (using the correct 'kern'
feature for CFF files), has ligatures etc. They also fix the missing
mappings for Romanian (no locl table yet...). The only troublesome
point may that the author of the conversion seems to want to remain
anonymous. The license of the fonts is still GPL. Here is the
copyright notice that accompanies them:

The OTF font files themselves have the original URW copyright.  Does
anyone have a problem shipping these with Fedora?
