Update of /cvsroot/python/python/dist/src/Lib/email
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv29677

Modified Files:
	Charset.py 
Log Message:
__init__(): Coerce the input_charset to unicode (with ascii encoding) before
calling .lower() on it.  This fixes the problem described in SF patch # 866982
where in the tr_TR.ISO-8859-9 locale, 'I'.lower() isn't 'i'.  unicodes are
locale insensitive.
