[Groff] Using non-ASCII characters in mom

[Per Edin]

Hi,

I'm having some trouble getting non-ASCII characters to work in my
mom-based documents. With pdfmom -k I get them to work without problem
in running text, but, when I use them inside quotes in .HEADING and
.TITLE I receive errors similar to:

noname.mom:60: can't translate character code 229 to special character
`oa' in transparent throughput
noname.mom:60: can't translate character code 229 to special character
`oa' in transparent throughput
noname.mom:60: can't translate character code 246 to special character
`:o' in transparent throughput

I'm lost, ideas to fix this are welcome. :)
