[Groff] typesetting Czech with custom fonts

[Petr Man]

Hello,

I am having trouble typesetting Czech. This is the first time I
actually tried a language with extensive punctuation.
I have a set of Gill Sans CE that contains the proper glyphs. I have
converted these to groff fonts as described in the mom docs.
However I still end up with errors and mangled text.
My typical command line looks like this:
pdfroff -M. -F. -Tps -p -t -e -g -R -s -k -Dutf8 -mmymom -mpdfmark
--report-progress --no-toc-relocation -dpaper=a4 -P-pa4
--pdf-output=rng.pdf rng.mom

I have also tried following:

cat rng.mom | iconv '-futf8' '-tlatin2' | groff -M. -F. -Tps -p -t -e
-g -R -s -mmymom > test.ps

stdin:161: can't translate character code 218 to special character
`'U' in transparent throughput
stdin:217: can't translate character code 225 to special character
`'a' in transparent throughput
stdin:217: can't translate character code 236 to special character
``i' in transparent throughput

But that still ends up in missing letters like the previous try
(specifically čřž etc.). This happens also with default groff fonts
(no glyphs?).
http://www.mail-archive.com/address@hidden/msg05273.html would probably
solve this for URW fonts (haven't tried yet, I want Gill Sans).

My question is whether this is caused by incorrect font conversion or
if the problem lies somewhere else.

I would be very grateful for any hints.
