Thank you for your reply. Your solution did not work, and I tried it already while searching for solutions. Linux and Windows or whatever OS should work equally on this issue, since Unicode was defined to be used widely, and not OS depedent. Everytime I had some problem I found a solution and then develop some routine or library to use everywhere for that context. In this case I'm going mad. I will see the other contributions to get a solution but my theory is still on the internal codifying of strings in Perl.
