interestingly that RFC seems to use UCS-2 interchanably with UTF-16
There was an excellent discussion of WTF-8 (like UTF-8 but with
surrogates) somewhere on the ineternet (I thought wikipedia, but I
can't find it now)
https://unicodebook.readthedocs.io/unicode_encodings.html
section 7.5. UTF-16 surrogate pairs
This bug is mainly motiviated by postgresql only accepting well formed
UTF-8. so UTF-8 that encodes uFE01 is rejected and leads to
mis-behaviour.
