[Groff] Special chars, german umlaute (again).

[Bruno Hertz]

Sorry to trouble you again guys, but I ran into problems once more.

More specifically, after installing groff 1.19.1 over my default
Redhat 9 groff 1.1.8.1-20 package, special chars won't come out right
any more.

As said my OS is RH 9 and my locale the default utf-8. Accordingly, my
groff input text files are all multibyte.

Now, with the (obviously heavily patched) Redhat groff package, all
special chars (umlaute) come out right in -Tps as well as with nroff.

groff 1.19.1 downloaded from the groff website on the other hand, while
printing standard ascii chars OK, outputs special chars as weird
two-char-combinations like ü, both via -Tps and nroff.

Looking at the Redhat patches, they are actually mostly concerned
with multibyte stuff. Question hence: since modifications seem
to be necessary to make groff properly work in an utf-8 environment,
are plans underway to fix this stuff?

For the records, I tried the same with iso-8859-1, and both groff
versions did OK. I.e. doing
 iconv -f utf-8 -t iso8859-1 text.utf-8 > text.iso
 nroff text.iso
 groff -Tps text.iso | ggv -
produces correct output with both groff packages (which implies that
the problem at hand is not critical but rather of interest to me).

Thanks, Bruno.
