Thank you very much. This is quite useful.

I could reproduce the problem with a 'Thèse' directory of my own. For
this particular case, the attached patch works for me. But it is likely
that the patch is not completely correct, and may break auto-hardstatus
for windows for some. I am weak on encoding issues, and I need to
test more to fine-tune the fix. In the meantime, if you could try it out
and let me know if this works you too, then that'd be great.

Also, help/suggestions about the encoding issue from anyone would also be
very welcome!

Cheers,
Sadrul
