Console ui "add" autocomplete crashes on unicode filename

[nullie]

Console ui crashes then I try to list options for add command autocomplete and directory contains unicode filenames, i.e.:

add /path/to/directory/with/unicode/entries/ <TAB> <TAB>

Traceback:

[ERROR   ] 23:17:28 screen:300 'ascii' codec can't decode byte 0xd0 in position 13: ordinal not in range(128)

UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 13: ordinal not in range(128)

That happens because os.listdir in deluge/ui/console/commands/add.py:94 gets encoded string, so it returns encoded strings as result, and screen.py doesn't handle encoded strings.

I could fix this, but don't know where should I do decoding (or make screen accept encoded strings).

Looks like it's broader problem, console doesn't support unicode input too

Add unicode input support

[nullie]

I've added a patch for unicode input support, it fixes autocompletion too. Don't know if it's correct though.

Applied to master, thanks!
