Yes. This can be especially nice when you need to use restricted charsets.

I needed to use unicode objects as Zope ids. But Zope only accepts a 
subset of ascii as ids.

So I used:


     hex_id = u'INBOX'.encode('utf-8').encode('hex')
     >>494e424f58

And I can get the unicode representation back with:

     unicode_id = id.decode('hex').decode('utf-8')
     >>u'INBOX'

Tn that case id.decode('hex') doesn't return a unicode, but a utf-8 
encoded string.
