 I had to solve this problem (with Type1 fonts always appearing as iso8859-1)
too when I was trying to use AW with russian. Solution is follows:
in fonts.dir list this font with adobe-fontspecific registry-encoding field,
and in fonts.alias make aliases from -adobe-fontspecific fonts to the font
with XLFD with encoding you need.

Example: you have a fonts named 'blah.pfa' and want to use it under the XLFD
-AbiSource-Arial-regular-r-normal--0-0-0-0-p-0-koi8-r, you do the following:

in fonts.dir you add:
blah.pfa -AbiSource-Arial-regular-r-normal--0-0-0-0-p-0-adobe-fontspecific

in fonts.alias you add:
-AbiSource-Arial-regular-r-normal--0-0-0-0-p-0-adobe-fontspecific -AbiSource-Arial-regular-r-normal--0-0-0-0-p-0-koi8-r
(two XLFDs on one line of course).

 After that you will really have glyphs in the font accessible by the XLFD
-AbiSource-Arial-regular-r-normal--0-0-0-0-p-0-koi8-r matching koi8-r
encoding. This is a feature of modern font servers and XFree4.x I believe.

 Of course they are available from gnome CVS. There are packages of it in rpm
format flying around (and even included in RedHat 7.0) under the name
