2003-02-25 Jeffrey Stedfast <fejj@ximian.com> * camel-mime-part-utils.c (simple_data_wrapper_construct_from_parser): canonicalise the charset name (if it is an iso charset) so that our strncasecmp to see if it is an iso-8859-# charset will be guarenteed to work on all systems. (canon_charset_name): New function to return the canonical iso charset name. (simple_data_wrapper_construct_from_parser): If the charset is NULL *or* the charset == "us-ascii" then check that it is 7bit clean to decide if it is rawtext (we did not check the case where charset was "us-ascii" before). svn path=/trunk/; revision=20057
