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.
