I am using Roundcube on Linux machine with Thai Language (TIS-620, WINDOWS-874) and everything is fine but I want to move from Linux to Solaris 11 machine however it seem character encoding on Solaris is not working. I install Squirrelmail to check that is postfix on Solaris is make wrong encoding but Squirrelmail is show language correctly.
Roundcube 1.2.7
Solaris 11.3
