Important (for big-endian servers):
    It has been discovered that before Firebird 2.5.2, CHAR_TO_UUID and UUID_TO_CHAR works
    incorrectly in big-endian servers. In these machines, bytes/characters are swapped and goes in
    wrong positions when converting. This bug was fixed in 2.5.2 and 3.0, but that means these
    functions now returns different values (for the same input parameter) than before.
