Uppercase is not a correct case folding for all unicode characters. See http://www.w3.org/International/wiki/Case_folding for details.

Of course, the only use of this feature I know of is a SQL parser, and there as in most programming languages, all identifiers are ASCII, so this is likely just pedantry.
