STINNER Victor <victor.stin...@haypocalc.com> added the comment:

About Python3, bytes.center accepts unicode as second argument, which 
is an error for me:

>>> b"x".center(5, b"\xe9")
b'\xe9\xe9x\xe9\xe9'
>>> b"x".center(5, "\xe9")
b'\xe9\xe9x\xe9\xe9'

The second example must fail with a TypeError.

str.center has the right behaviour:

>>> "x".center(5, "\xe9")
'ééxéé'
>>> "x".center(5, b"\xe9")
TypeError: The fill character cannot be converted to Unicode
