imo (as the original author of the unicode type), that's an =
artifact, not a feature.

the original Unicode type used UCS-2 for internal storage, and all =
operations worked on code points.

adding UTF-16 support in a couple of places doesn't really change that;
an UTF-16-encoded unicode string should be treated just like an encoded
8-bit string -- standard string operations are not guaranteed to work on
encoded strings.

(if we document all bugs and half-baked solutions as supported features,
we will never be able to fix anything...)
