Why would PEP 393 apply to other implementations than CPython?
Not the PEP itself, just the implications of the result. The question was whether the language specification in a post PEP-393 can (and if so, should) be changed into requiring unicode objects to be defined based on code points. Narrow builds, as well as Jython and IronPython, currently deviate from this as they use UTF-16 as their native string encoding, which, for one, prevents O(1) indexing into characters as well as a direct match between length and character count (minus combining characters etc.). I think this discussion can safely be considered off-topic for this thread (which isn't exactly short enough to keep adding more topics to it). Stefan
