Hmm. The error message you posted is not as clear as it could be. It is
printed when the charset conversion of the received diff data fails. In
detail: we need to convert the data we receive from the diff command
into UTF-8 because the internal buffer always uses UTF-8. And we assume
the data we receive is in the same encoding as the file which was
passed to the diff command (i.e. the current file).
If the current file is already in UTF-8 and you get this message, then
there is really something wrong ;-(.

Ok, this message is also not very useful (I'll change it tomorrow to
be more descriptive).
This message is caused by errors when spawning new processes (cvs.exe
in this case). IIRC there were some not really critical errors reported
by the Win32 API but the new process was spawned correctly anyway.

So, could you start Geany with the command line option "-d" and
test again with both plugins? Then an additional console window will
open and some more messages are shown, especially of the encoding
conversion code.

Thanks.

Regards,
Enrico
