_PyUnicode_CheckConsistency() checks that the contents of the string
matches the _KIND of the string. However it does this in a very strict
manner, ie. that the contents *exactly* match the _KIND rather than just
detecting an inconsistency between the contents and the _KIND.
For example, a string created with a maxchar of 255 (ie. a Latin-1
string) must contain at least one character in the range 128-255
otherwise you get an assertion failure.
As it stands, when converting Latin-1 strings in my C extension module
I must first check each character and specify a maxchar of 127 if the
strings happens to only contain ASCII characters.
What is the reasoning behind the checks being so strict?
