[Freeswitch-users] Invalid UTF-8 character

Hi All, Anybody have idea, what could cause this WARNING.. I am getting this one since i upgraded to latest git last week, dont know if its related to that though. *switch_xml.c:2329 Invalid UTF-8 character to ampersand, skip it* There are 100s of such lines getting printed on each call. So want to fix the same before i make it live. Thanks a lot.
