[issue5127] UnicodeEncodeError - I can't even see license

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

Since r56395, ord() and chr() accept and return surrogate pairs even in
narrow builds.

The goal is to remove most differences between narrow and wide unicode
builds (except for string lengths, indices or slices)

To address this problem, I suggest to change all functions in
unicodectype.c so that they accept Py_UCS4 characters (instead of
Py_UNICODE). 
This would be a binary-incompatible change; and --with-wctype-functions
would have an effect only if sizeof(wchar_t)==4 (instead of the current
condition sizeof(wchar_t)==sizeof(PY_UNICODE_TYPE))
