Add the CAMEL_BESTENC_TEXT bit to enctype if the part is a text part.
2003-06-09 Jeffrey Stedfast <fejj@ximian.com> * camel-mime-message.c (find_best_encoding): Add the CAMEL_BESTENC_TEXT bit to enctype if the part is a text part. * camel-mime-filter-bestenc.c (camel_mime_filter_bestenc_get_best_encoding): If we have any nul-bytes or if the content is non-text and contains any 8bit octets, we need to use base64. Fixes bug #44344. svn path=/trunk/; revision=21409
