Replicate the semantics of the libunicode utf8 functions by returning NULL
2001-05-14 Jon Trowbridge <trow@ximian.com> * camel-search-private.c (utf8_get): Replicate the semantics of the libunicode utf8 functions by returning NULL in the arg on invalid utf8. * camel-pgp-context.c (pgp_verify): Check for valid utf8, terminate loop if something looks wrong. * camel-mime-utils.c (header_encode_phrase_get_words): Properly check for invalid utf8. (header_encode_string): Properly check for invalid utf8. * camel-charset-map.c (camel_charset_step): Properly check for invalid utf8. 2001-05-14 Jon Trowbridge <trow@ximian.com> * e-html-utils.c (is_citation): Check for bad utf8. svn path=/trunk/; revision=9798
