[web2py] Re: save the original value of one field in another table field
This is generally not good database design. What are you really trying to
do? Would it make more sense for mytable2 to reference mytable?

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.

[web2py] Re: field username in auth_user
By default it must match the following regular expression: '[\w\.\-]+' So, no spaces. I suppose you could override the default validator and allow spaces, but I'm not sure if that has any consequences for uses of the username elsewhere in the Auth system.

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).

[web2py] Re: Clarification please on autocomplete widget...
Thanks, Anthony.
because there may be MANY values in the field, what I would actually be
perfectly happy with is a list as you describe it,
but one that is the result of a db query,
e.g. a list of names of all schools whose "Field('district_id' ,
'reference districts', label=T('District')" is 2.
Tried doing that yesterday without success.

No, as the example in the book shows, by "list", it just means a list
generated from the contents of a single field in a database table (in
contrast to the reference field option, which submits integer ID values
from a reference field but searches and displays the corresponding values
from an alternative field).
