Yes, I know that ,but that's not problem...look below...

UTF-8, but question is why 3.1.1 (and 2.6.4) returns correct result but 
3.0.0 NOT with same project and same settings.

Another thing is that project when running from IDE with fpc-3.0.0 
doesn't get correct result even for GetEnvironmentVariableUTF8(), while 
3.1.1 is correct again.
