SIP Messages are parsed using system encoding instead of UTF

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Send INVITE to application with UFT-8 display name in From header
2. Get request.getFrom().getDisplayName()

What is the expected output? What do you see instead?
Name contains invalid chars, but it should be parsed using UTF encoding.

What version of the product are you using? On what operating system?
mobicents-sip-servlets 2.1 on windows 7

Please provide any additional information below.
Problem disappear if I add "-Dfile.encoding=UTF-8" to application, but I think 
library should parse messages using UFT encoding despite to system encoding.

Can you attach a log file at DEBUG level showcasing the full call flow ?
