[syslog-ng] XML entities in PatternDB

[Martin Holste]

I'm trying to find a way to use non-printable characters to delimit
messages to avoid problems with escaping message delimiters.  However, I'm
having trouble representing any special characters in the patterndb.xml
file.  Specifically, I'd like to use characters like those found here:
http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references#Character_entity_references_in_HTMLsuch
as U+200C.  Trying to use the XML entity name, ‌ results in an
error: "Entity name \'zwnj\' is not known."  Is there a place that lists
what entities are allowed in the XML?

Thanks,

Martin
