+Optimized Unicode Representation
+--------------------------------
+
+CPython 3.3 will use an `optimized unicode representation`_ which switches between
+different ways to represent a unicode string, depending on whether the string
+fits into ASCII, has only two-byte characters or needs four-byte characters.
+
+The actual details would be rather differen in PyPy, but we would like to have
+the same optimization implemented.
