Tiago R. Espinha commented on DERBY-728:
----------------------------------------

At the risk of pointing out the obvious, I tested this on the 10.5 RC1 using ij and the issue does not arise.

Interestingly enough, the folder that is created for the database seems to have the Unicode representation of the character and is just called: u4e10

I'm just wondering whether it isn't somehow assuming the u4e10 as a string literal rather than a Unicode character.
