You always have to know locale to handle case conversion - this is not actually defined the same way in different human languages and it is a mistake to pretend it is.

In most cases locale is encoded in character itself, i.e. Latin "a" and Cyrillic "a" are two different characters, despite being visually indistinguishable in most cases.
The "language-sensitive" section of the special casing document [0] is extremely small and contains only the cases of stupid reuse of Latin I.
