Yes, but PyUnicode_FromFormatV() uses UTF-8 decoder with replace error handler, and so the incomplete byte sequence will be replaced by � (it doesn't fail with an error). Example: >>> "abc€".encode("utf-8")[:-1].decode("utf-8", "replace") 'abc�'

Yes, but PyUnicode_FromFormatV() uses UTF-8 decoder with replace error handler, and so the incomplete byte sequence will be replaced by � (it doesn't fail with an error). Example:

>>> "abc€".encode("utf-8")[:-1].decode("utf-8", "replace")
'abc�'
