From http://www.columbia.edu/kermit/utf8.html:

  UTF-8 is an ASCII-preserving encoding method for Unicode (ISO 10646),
  the Universal Character Set (UCS). The UCS encodes most of the world's
  writing systems in a single character set, allowing you to mix languages and
  scripts within a document without needing any tricks for switching character
  sets. This web page is encoded directly in UTF-8. 

So, if I understand correctly, since we specify UTF8 as our
encoding, a RequestContext in Unicode and a Policy in ASCII will
compare nicely.
