Thank you.
I already decide to use Mule-Internal encoding. In fact, there is no 
other choice. But I'm still not sure that I can solve my problem with 
mule -internal encoding.

1. How can I copy(or backup) mule-internal encoded data. Mule-Internal 
is for just back-end. If there is a table that have rows in many 
different kind of language. I think, I could not back it up. Am I wrong?

2. I think Unicode is better then mule-internal. So, I will use unicode 
encoding as soon as postgresql support automatic unicode translation. At 
that time, should I translate mule-internal encoded table to unicode. ( 
I know there is positive side in mule-internal. One is It store string 
with it's char set code. So I can distinguish the original char set of 
character string. Another is postgresql use UTF-8 to store Unicode data. 
It has a lot of over head when you encode CJK char. string.)

3. I don't know how postgresql sort mule-internal encoded data. Mule- 
internal is not another char set. It just store 2 byte char  with it's 
char set code. I mean it store 1 character(2bytes) in 3 bytes. I just 
guess, postgresql may sort data by it's char set, first.
