[issue10521] str methods don't accept non-BMP fillchar on a narrow Unicode build

[Eric Smith]

Eric Smith <eric at trueblade.com> added the comment:

str.__format__ and friends (int, float, complex) also have this same problem. For example, when they're computing the "fill" character:

>>> format('', 'x^')
''

>>> format('', '\U00100140^')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: Invalid conversion specification
