Subject: __init__(): Coerce the input_charset to unicode (with ascii encoding) before
X-Git-Tag: v2.4b1~65

__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.
