Search the changelob or 3.3 misc/News for items affecting those two 
modules. There are at least 4.
http://docs.python.org/3.3/whatsnew/changelog.html

It is faintly possible that the switch from narrow/wide builds to 
unified builds somehow affected that. Have you tested with 2.7/3.2 on 
both narrow and wide unicode builds?
