I had the impression that we were abolishing the wide versus narrow build difference and that this issue would disappear. I must have missed something. Most certainly. The PyUNICODE type continues to exist for backwards compatibility. It is now always a typedef for wchart, which makes it a 16-bit type on Windows.

Thank you for answering: My revised impression now is that any string I create with Python code in Python 3.3+ (as distributed, without extensions or ctypes calls) will use the new implementation and will index and and slice correctly, even with extended chars. So indexing is only an issue for those writing or using C-coded extensions with the old unicode C-API on systems with a 16-bit wchar_t. Correct?
