(Noting that their definition of "character" is probably "a 16-bit
value of type char", and has only fleeting resemblance to what is or
is not defined as a character by the Unicode standard.)

Without having digested the entire discussion, this sounds like a good
solution for Python too.  The "==" operator should compare strings
based on a simple-minded representation-oriented definition, and all
the other stuff gets pushed into separate methods or classes.
