Does Python 2.5.2 follow Unicode for lower() and upper()?

Question

I'm making a Google AppEngine Application. Does the Python 2.5.2 runtime environment follow the Unicode Standards? (For example, the lower() and upper() methods on unicode objects.)

Answer 1

Yes and no.

For an example, see the code being discussed here: http://stackoverflow.com/questions/727507/how-can-i-do-unicode-uppercase-in-python
