encoding error

Hello,

I try to insert some japanese text in my database. But it fails with
duplicate value error, although I use two different values. My database
is set up with UNICODE, I even tried a SQL_ASCII set up where I do all
conversion manual, but nothing worked, the error persists. Please find
the smallest possible example attached below.

I verified it in 7.4.7 and 8.1.

Any ideas welcome!

TIA

Ulrich
