bsddb throws a TypeError when I try to use an unicode string as key name;
i.e. bsddb.btopen("foobar", "c")[u'foo'] = "bar" fails

I discovered it while experimenting with the shelve module. You may find more information in the attached file.

Python version: 2.5.1
OS: Windows XP SP2 (5.1.2600)

Unassigning since I don't know the details of bsddb.

The BerkeleyDB library operates on bytes only.  Unicode doesn't make
sense as a key without converting it to a particular encoding first. 
Use the unicode object's encode() method if you need to use it as a
database key or create a wrapper object or subclass of the db that
automatically does that for you as appropriate.
