As a data point, ICU defines U16_NEXT() for similar purpose. I also
like ICU terminology for surrogates ("lead" and "trail") better than
the backward "high" and "low". The U16_APPEND() suggests
Py_UNICODE_APPEND instead of PUT_NEXT (this one has a virtue of not
having "next" in the name as well.) I still like NEXT better than
ADVANCE because it is shorter and has an obvious PREV counterpart that
we may want to add later.
Note that ICU uses U16_ prefix for these macros even when they operate
on 32-bit characters.
