Description Josh Bressers 2006-09-26 18:10:30 UTC
A bug in the way python's repr function handles certain unicode objects.  repr
mistakenly assumes that all unicode characters will be 6 characters in length
(UTF-16) when it is possible for some strings to use wide characters (UTF-32) to
overflow a buffer.
