DaeMyung Kang updated TAJO-307:
-------------------------------

    Attachment: TAJO-307.patch

Please review this.

It's operations is somewhat different from posgresql's
I just limit it's bound from 1 to 65525(Unicode UCS2 range)

but postgresql allow to input until 2097151(but it just returns "")

so I need some advice.
Should we make this function like postgresql's?
