The default validators for the username field are:
[IS_MATCH('[\w\.\-]+', strict=True,
error_message=self.messages.invalid_username),
IS_NOT_IN_DB(db, '%s.username' % settings.table_user_name,
error_message=self.messages.username_taken)]
You could replace the IS_MATCH with a custom validator that accepts unicode
characters, or just remove IS_MATCH altogether.

Also, chapter 7.9 describes the tools for getting unicode properties, and you can find the numeric value for a given character that way. I would expect the DAL connectors to handle most of the common encodings, and Leonel points out they can talk UTF-8 to a database that supports it (find me an example that doesn't). In the book, the DAL signature shows UTF-8 as the default codec. http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer?search=unicode#DAL-signature> If you really need to be ASCII-safe: Since URLs are supposed to be ASCII, unicode gets escaped ... look at chapter 20.5.2 for urllib.quote(): https://docs.python.org/2.7/library/urllib.html#utility-functions> or the web2py helper function xmlescape() http://web2py.com/books/default/chapter/29/05/the-views#xmlescape> to provide a "clean ascii" representation if you need to. I know, TL;DR. But I hope this gives you some pointers to your choices.

[web2py] Re: managing latin characters
Web2py uses utf-8 everywhere by default, you don't need to worry about it. If you're smart you will use utf-8 in the database too and everything pretty much just works, otherwise you will just have to tell the DAL about the encoding the database uses using db_codec. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
