It is not. Not directly, anyway.

No, it is not. :-)
Groff supports various single-byte encodings for input; see `Input
Encodings' node in `info groff'. To handle UTF-8 input, groff (1) has a
-k option that uses preconv(1).
$ printf ä | hd # I use UTF-8 here.
00000000 c3 a4 |..|
00000002
$
$ printf ä | groff -k -Tutf8 | grep .
ä
$
Cheers, Ralph.
