[issue10830] PyUnicode_FromFormatV("%c") doesn't support non-BMP characters on narrow build

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

PyUnicode_FromFormatV("%c") supposes that an unicode character is always stored as a single Py_UNICODE word: but that's wrong on narrow build with characters in [U+10000; U+10FFFF].

Attached patch fixes this bug.

See also #10829.
