[Python-Dev] Difference between PyUnicode_IS_ASCII and PyUnicode_IS_COMPACT_ASCII ?

[Antoine Pitrou]

Hello,

The include file (unicodeobject.h) seems to imply that some pure ASCII
strings can be non-compact, but I don't understand how that can happen.

Besides, the following comment also seems wrong:

       - compact:

         * structure = PyCompactUnicodeObject
         * test: PyUnicode_IS_ASCII(op) && !PyUnicode_IS_COMPACT(op)

Regards

Antoine.
