* Unicode fixes: when using mysql_enable_utf8 or mysql_enable_utf8mb4,
  previous versions of DBD::mysql did not properly encode input statements
  to UTF-8 and retrieved columns were always UTF-8 decoded regardless of the
  column charset.
  Fix by Pali Rohár.
  Reported and feedback on fix by Marc Lehmann

  mysql_stmt_fetch() call. But it does not update pointer to that buffer in

=item mysql_enable_utf8mb4

This is similar to mysql_enable_utf8, but is capable of handling 4-byte
UTF-8 characters.

=item mysql_bind_type_guessing

This attribute causes the driver (emulated prepare statements)
to attempt to guess if a value being bound is a numeric value,
