package unrtf in debian/ubuntu  universe might help with this - it has 
command line to convert to plain text - anyone wanna write a filter for 
this?

hum,

Questo ?? un semplice esempio delle potenzialit?? di OO.o

A question: what is encoding of this string? UTF8, ISO-something,
Win-something, etc.? Now, I can see that with libGSF and a RTF file:

Doc.Comment="Questo file altro non \303\250 che un esempio di modello di
file per OO.o Writer per testare l'indicizzazione di Tracker";


Thanks.


It is not possible to remove extra output (except with shell commands of
course)... Perhaps we should extract some parts of its source code.

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.
