def isascii(unicode string not None):
"""Return ``True`` if all characters in the string are ASCII.
ASCII characters have code points in the range U+0000-U+007F.
Note:
On Python 3.7+, this function is just aliased to ``str.isascii``.
This is a Cython fallback for older CPython versions. For longer strings,
it is slightly less performant than the built-in ``str.isascii``.
Args:
string (str): A string to test.
Returns:
``True`` if all characters are ASCII, ``False`` otherwise.
