Comment (by dukebody):

 @coldmind, I've found the following:

 {{{
     >>> MySQLdb.escape('', MySQLdb.converters.conversions)
     "''"

    >>> MySQLdb.escape(u'', MySQLdb.converters.conversions)
     ''
 }}}


 And the default parameter for `blank=True` `CharFields` is an unicode
 string (checked that with pdb, Django 1.7). So is MySQLdb escaping unicode
 strings incorrectly, or should the default parameter be a bytestring
 instead?
