Keuntae Park commented on TAJO-382:
-----------------------------------
Sorry, I have a mistake on understanding unicode conversion.
As '\034' is octal code, it is 28 and its unicode equivalent is '\u001C'
So, the returned result of decode('0x0a0x1C0x09', 'hex'), '\n\u001C\t', is just
unicode expression of '\n\034\t'.
I think there is no problem.
