[Python-Dev] Use of %c and Py_UNICODE

[A.M. Kuchling]

unicodeobject.c contains this code:

                PyErr_Format(PyExc_ValueError,
                            "unsupported format character '%c' (0x%x) "
                            "at index %i",
                            c, c, fmt -1 - PyUnicode_AS_UNICODE(uformat));

c is a Py_UNICODE; applying C's %c to it only takes the lowest 8 bits,
so '%\u3000' % 1 results in an error message containing "'\000'
(0x3000)".  Is this worth fixing?  I'd say no, since the hex value is
more useful for Unicode strings anyway.  (I still wanted to mention
this little buglet, since I just touched this bit of code.)
