Sure, but I fear that Robin's objection is still valid.  Unicode
treats Turkish as an exception too, see:

   http://unicode.org/Public/UNIDATA/CaseFolding.txt

As far as I understand you have to know in advance whether you are
typesetting Turkish.  A static table for all languages isn't
sufficient.

It would be much more convenient if case folding wouldn't depend on
the language, i.e. the Turkish "i" had a separate code point.

However, I think it's solvable.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
