That's what I thought, and this is how it works with ttf fonts -- you
specify iso8859-1 and get iso-8859-1 font, and if you specify iso-
8859-8 you get a Hebrew font and and if you specifiy iso10646-1
you get a unicode font. But with the postscript font irrespective of
what encoding I specify in the encoding field, the font behaves like
an iso8859-1 font.

I though about that too, but there are no links to gtk 2 sources on
the gtk website ... If I recall corretly, Pango might use font sets as
well as proper Unicode fonts; the problem with fontsets is that it
would require much more significant rewrite of our code, and that
IMHO font sets are anachronistic, and by the time utf-8 locales will
become the standard, there will be no need for font sets, because
there will be enough Unicode fonts.
The input and drawing for utf-8 are already implemented, you just
need to use ttf fonts; that's why I am so keen to be able to print ttf.
I personally am quite happy to use ttf fonts and there are virtually
no free Type1 Unicode fonts around anyway.
