I think it's the right way for a solution. Now my page is utf-8, but if
the string returned from MessageCatalog have utf-8 chars and not online
chars in ascii range I get this error-message:

*Error Type: UnicodeEncodeError*
*Error Value: 'ascii' codec can't encode character u'\xf4' in position
3: ordinal not in range(128)*
