from unrtf manual:  "All output formats except HTML are "alpha" i.e.
limited and development has just begun" (see `man unrtf`). The program
was previously know as rtf2htm.

It seems that HTML output is better (unrtf info are in <!-- -->
comments) but I've an old version (0.19.2 on edgy) and there are still
issues in accented characters and \keyword content ( \subject and
\doccomm seems missing)

The latest (0.20.2) seems to support Unicode, maybe we should contact
unrtf maintainers and provide them bugreport.
