I see that this misconception widely spread. In fact Python 3.3 uses
four kinds of ready strings.
* ASCII. All codes <= U+007F.
* UCS1. All codes <= U+00FF, at least one code > U+007F.
* UCS2. All codes <= U+FFFF, at least one code > U+00FF.
* UCS4. All codes <= U+0010FFFF, at least one code > U+FFFF.
Indexing is O(0) for any string.
Also the string can optionally cache UTF-8 and wchar_t* representation.
