[Icecast] xmlEncodeEntitiesReentrant error

[chip]

hi

has anyone seen this error before:

[root at machine root]# error : xmlEncodeEntitiesReentrant : input not UTF-8

unfortunately i cannot see what application is causing this error but i
suspect that it is icecast because of the XML config file and we have made
some changes recently.  i have issued thess commands to try to get
something from the logs:

[root at machine root]# grep -r -i xmlEncodeEntities
/usr/share/icecast/icelog/error.log
[root at machine root]#

[root at machine root]# grep -r -i xmlEncodeEntities /var/log/
[root at machine root]#

but i get nothing back unfortunately.  i have done the usual googling but
it appears that this xmlEncode error can be generated by a number of
different applications?

my scripting isn't so good so i don't know how to parse the icecast.xml
file to highlight the non UTF-8 encoded characters - has someone got any
idea as to how to do this please?

bests and thanks in advance.
