[xml] Workaround for bug 159547: escaping versus UTF8 in xmlNodeDump

[Jose Gonzalez <jgon etb bel alcatel be>]

Hello,
 I recently discovered in my application the effects of Bug 159547 
(http://bugzilla.gnome.org/show_bug.cgi?id=159547), that is, UTF-8 
characters get escaped.
My application performs an xmlNodeDump (from function curDumpNode, code 
below) to store the results in database, I do not need to store the 
escaped characters.
In the bug page it is mentioned that one can modify this default 
behavior (UTF-8 getting escaped) using the API, but I have not been able 
to do so.
Does someone have an example of using the API to disable the UTF-8 escaping?
Regards,
 Jose
