How to convert Unicode string to raw string escaped with HTML Entities

[ldng]

Hi,

I'm looking for a way to convert en unicode string encoded in UTF-8 to
a raw string escaped with HTML Entities. I can't seem to find an easy
way to do it.

Quote from urllib will only work on ascii (which kind of defeat the
purpose imho) and escape from cgi doesn't seems to do anything with my
string.

Any suggestion ?
