Poking around a little more in RFC4616, I see a reference to SASLprep
(RFC 4013) and StringPrep (RFC 3454). Apparently, the correct
normalization is NFKC; however, that is considered optional, and
reading between the lines a bit, I think this normalization, if done
at allo, is intended to happen in the server – just prior to computing
the hash.
If I have that right, TRT on the client side is to just pass the
string through unchanged. Which is a relief.
Apologies for not doing this small bit of research before raising the
issue.
