It seems that when doing 'a % b' where a is a normal string and b is a
Unicode string, the result will be a normal string where b appears 
UTF-8-encoded. IMHO this is the Wrong Thing, since Unicode strings should
always appear as Unicode unless the code explicitly requests something
else.

Also, this differs from the behaviour of the corresponding approach using
+.

The interpreter dialog below should explain.
