Because you might not always want to encode in UTF-8. If you'd like to 
display a cyrillic URL to the user in a web page (not in an href), then 
you'd want KR-8 or whatever it is.

No, I think there's a quite easy solution. AbsoluteURL.__call__ should 
return unicode so that one has all the options when using it from 
Python. AbsoluteURL.__str__ should return whatever __call__ would 
return, but encoded in UTF8. If I remember correctly, TALES first 
evaluates __str__ before __call__, so the path expressions would still 
be fine.
