[fpc-pascal] Does Free Vision support utf8 on unix?

[Juan Francisco Cantero Hurtado]

Does Free Vision support utf8 on unix? This example builds fine on Linux 
but the second messagebox shows weird symbols:

program TestFV;
uses App, MsgBox;

type
          TMyAPP = object(TApplication)
          end;
var
          MyApp: TMyApp;
begin
          MyApp.Init;
          MessageBox('aeiou', nil, mfWarning or mfOKButton);
          MessageBox('áéíóú', nil, mfWarning or mfOKButton);
          MyApp.Run;
          MyApp.Done;
end.

Is this bug known or should I report it in the bug tracker?
