Maybe I'm mistaken, but I've been a troff user for some time now (>15 y.?)
and I remember that when I shifted from DWB troff to groff (a great
shift, that goes without saying), I found out that all accents and
dieresis marcs, cedillas, etc. are inverted under groff. That is:

    ditroff              groff
    \(a`                 \('a
    \(U:                 \(:U
    \(c,                 \(,c
    etc.                 etc.

So I had to filter text in oder to put the correct accents. Could
this be the same problem?
