everytime i search for customers with special characters like "äüöß" i get an AJAX error (Screenshot). It seems that AJAX cant convert special characters to JSON. Here is the Apache errorlog:
[Tue Dec 02 14:38:46.904437 2014] [cgi:error] [pid 2245:tid 140183580116736] [client 10.3.139.43:51789] AH01215: malformed or illegal unicode character in string [\xc2\x84tzlmeier ], cannot convert to JSON at /opt/otrs/bin/cgi-bin/../../Kernel/System/JSON.pm line 97., referer: http://otrs/otrs/index.pl?Action=AgentTicketEmail

I use an external MSSQL database with "SQL_Latin1_General_CP850_CI_AS" encoding. In older OTRS versions there werent any problems with the conversion(3.0-3.3).
Any help will be appreciated
Sorry for my bad english but its not my mothertongue
