The problem of coverting filename with the Chinese character

[mintow]

My MediaWiki has so many pages with Chinese character.
Running yamdwe.py, and I got an error:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 5: ordinal not in range(128)

I added some code as follow:
dokuwiki.py about L87
full_title = full_title.decode('utf-8')
wikicontent.py about L180
pagename = pagename.decode('utf-8') text = text.decode('utf-8')

And I got another error:

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-3: ordinal not in range(128)

I think it's because of the Chinese character in pagename/titlename.
I also failed when replace the decode() with urllib.quote(),
Do you have any other suggestions?
