Programming in multiple encodings, I've been thinking this for a while.
Currently I'm looking at using comment or some special directive like
(declare (source-encoding "utf-8")) 

Python adopted encoding-specifying comment, e.g.

    #!/usr/bin/python
    # -*- coding: <encoding name> -*-

see http://www.python.org/peps/pep-0263.html for the details.
