Cannot authenticate with accented chars

[anonymous]

If there is an accented char (like ò) in the login field, the authentication fails with the following error (see the last row):

Trac[store] DEBUG: LDAPAuth: Unexpected error: Traceback (most recent call last):

UnicodeEncodeError: 'ascii' codec can't encode character u'\xf2' in position 39: ordinal not in range(128)

May be a solution could be to encode('utf-8')? ​http://stackoverflow.com/questions/1652904/unicodeencodeerror-ascii-codec-cant-encode-character

If this cannot be fixed in the TracLdapAuthPlugin code, what can be done to avoid this issue? Thanks
