	* Charset-DecodeHandler.t: Cases for charset names has
	been changed to match with the module's implementation.

2007-07-15  Wakaba  <wakaba@suika.fam.cx>

++ whatpm/Whatpm/Charset/ChangeLog	15 Jul 2007 16:49:53 -0000
	* DecodeHandle.pm (create_decode_handle): Set canonical
	or specified name to |input_encoding| attribute.
	(uri_to_name): Reimplemented.
	(input_encoding): Return charset name returned
	by |uri_to_name| if available.
	($CharsetDef): Property |xml_name| is now contain
	only name defined in XML specifications.
