> '_' matches a single collation element rather than a single character if multiple characters
have a single collation element.  Below is an example with norwegian aa  This occurs also
with the patch for DERBY-2967 which addresses the case of matching of a  single character
having more than one collation element.

> 0 rows inserted/updated/deleted
> ij> insert into t values('middleaavalue');
> 1 row inserted/updated/deleted
