The second line at the top has "For full details, see the changelog."
where changelog links to
http://docs.python.org/3.4/whatsnew/changelog.html
Searching that for 'UTF-34' goes to this line
"Issue #14625: Rewrite the UTF-32 decoder. It is now 3x to 4x faster.
Patch written by Serhiy Storchaka." where 'Issue #14625' links to
http://bugs.python.org/issue14625
with full discussion. (I know that you, Mark, could have found that, but
not everyone reading could.)
