19998,Feeds can contain characters that are not valid XML,westi,,"It is possible for any of the feeds to contain control characters which are not valid in XML e.g. http://www.fileformat.info/info/unicode/char/1c/index.htm

When outputting user supplied content in an XML context we should strip these control characters - they are unprintable and just break feed parsers.

http://en.wikipedia.org/wiki/Valid_characters_in_XML has a good list of what is and isn't valid.

I guess we need a {{{strip_for_xml()}}} function or something.",defect (bug),new,normal,Awaiting Review,Feeds,3.3.1,normal,,has-patch,westi luke.gedeon@…
