David,

<< I decided to modify the WHERE clause in the triggers after all.  But did
some testing and reading of the manual (what a concept!) and learned a lot
about collation and constraints.  In fact, I put a short "knowledgebase
posting" on this subject in the SQL group to help this stick in my head. >>

Thanks, that is helpful.

<< Tim, thanks again for your awesome extra-mile help on this! >>

No problem.  I'm glad that everything is working okay now.
