Its *very* ugly, but im pretty sure you can make it look prettier.

import htmlentitydefs as entity

s = u"© and many more..."
t = ""
for i in s:
     if ord(i) in entity.codepoint2name:
         name = entity.codepoint2name.get(ord(i))
         entityCode = entity.name2codepoint.get(name)
         t +="&#" + str(entityCode)
     else:
         t += i
print t

Hope this helps.
