File metadata containing invalid characters produce bad-formed XML
Closed, ResolvedPublic

Description

See url. The file contains a bare 0x0F character \x0f on the title field which is passed untranslated through the API to the user as XML. It would be bad if this were an invalid unicode char, but being < 32, per http://www.w3.org/TR/REC-xml/#charsets its presence makes the full api result not well-formed, choking XML parsers on it.
