This isn't the solution to your problem, but it might give you some ideas:

  http://skew.org/xml/stylesheets/url-encode/

It essentially uses string-length() and substring-before() to find the
index of a character in a string, then applies a little arithmetic on
that number to arrive at character indices in another string to produce
the output.

If your goal is to produce UTF-8 sequences, it will be a little trickier,
and you are going to have to decide what reasonable subset of Unicode is
worth supporting in this manner, but it should be possible in pure XSLT.
