[Freeswitch-users] Invalid UTF-8 character to ampersand, skip it

Hi, I've just installed freeswitch on windows using the binary install (FreeSWITCH Version 1.0.head (git-6ab3f56 2011-12-28 16-52-30 -0600). Whenever a call is made the log fills up with about 42 "Invalid UTF-8 character to ampersand, skip it". I haven't changed any config from the default. Any pointers ? Thanks! Ryan
