- Stabilize them
- While it’s the technically correct term, I suspect many users don’t know or care what exactly a code unit is.
- UTF-16 handling is simple and stable enough that it belongs in
- People are asking for it
- UTF-16 decoding is already stable, through
Only slightly related, but while we’re at it: change
char::encode_utf16 to return iterators, and stabilize them.
There is precedent of returning “short” iterators in e.g.
char::lowercase. This also means there is no need to expose a generalized
Utf16Encoder that takes any
char iterator as input, one can use
