You should be *encoding* what you print. The system file handle and HTTP can only deal with bytes, which means the characters much be converted from Perl's internal string format (as returned by mysql_enable_utf8 => 1) into bytes by encoding them. 

print encode("UTF-8", "$row[0]\t$row[1]\n");

or 
binmode(STDOUT, ':encoding(UTF-8)');
print "$row[0]\t$row[1]\n";
