For instance, Czech UTF8 input (attached), will come out as garbage.

groff -Tps   text.t >
groff -Tpdf  text.t > text.pdf
groff -Tutf8 text.t > text.utf8

AFAIK, the input has to be preprocessed by preconv(1),
invoked by groff -k; is that what you meant? Then

        groff -k -Tutf8 text.t > text.utf8

outputs the input, while

        groff -k -Tps   text.t >
        groff -k -Tpdf  text.t > text.pdf

complain about

        troff: text.t:1: warning: can't find special character 'u0072_030C'

- I probably miss the fonts that groff would use for these characters.

Anyway, UTF8 is UTF8; I don't understand why there would be a difference
for this or that language, if UTF8 covers characters of both.
