Recommended practice: Implementations should return a value that represents
an en-
coding whose code unit size matches the size of a single wchar_t.

"Obviously broken" is a rather big claim in the absence of suitable
alternatives.
I believe the use of the IANA registry is motivated by the paper and
previous polls.
I did however modify the paper to use more correct terminology and added a
note to explain that our terminology differs, which will hopefully avoid
confusion
