Hi!
I had a problem - embedded bittorrent client corrupted names with unicode (non-ASCII) characters. The problem was due to system-wide ASCII C locale setup.
To solve the problem I added at the beginning of bittorrent startup script /etc/init.d/bittorrent.sh:
export LANG=C.UTF-8
That instructs standard C library to work in unicode locale.
I hope the unicode issue would be solved in future firmware releases out-of-box.
