This is not really the Bugzilla support forum. This sounds to me like a weird mix of local network problems and weird server configuration. What steps have you taken to identify that this is a problem with Perl?	[reply]

Hi Antoine :) Seems to be an encoding problem ("wide character"). Try to save the output in binmode and UTF8. http://stackoverflow.com/questions/2468533/how-do-i-eliminate-tts-wide-character-in-print-warning	[reply]
