> I think Code needs to be added to opensource/java/engine/org/apache/derby/impl/sql/compile/LikeEscapeOperatorNode.java
> to disable like optimization for databases with non-default collation.  There is left
over code in this routine that says it disables it for national char by adding a cast to one
of the two sides which I assume then stops some other code from considering the 
> optimization.
