Now that Tanktalus has answered your questions, I'd be curious to understand what you mean when you say:

I want to use simple Unicode case mapping and not the default full case mapping.

When I use Unicode strings in perl, I consider "simple Unicode case mapping" to be the same thing as "default full case mapping". But you seem to mean something else by it, so I'm confused.

I'm also curious whether you really intended to use "0044" as the third element being returned by your "ToUpper" sub. Did you really want uc("abcdef") to return "DEFdef"?
