example:
create table t1(a graphic(64)) organize by column
insert into t1 values
(X'e0b885e0b886e0b887e0b885e0b886e0b885e0b886e0b885e0b886e0b885e
0b886e0b885e0b886e0b885e0b886')
SELECT hex(CAST(a AS CHAR(10))) FROM t1
returns xE0B885E0B886E0B887E0
where last byte, xE0 is partial and not a valid character.
we should have returned
