   You could go ultra-conservative and create a function taking two
arguments, both strings, which will replace any character in the
second string with a numeric reference if that character is not in
the first string.  For the first string, have just the printable ASCII
characters, minus &, < and >.
   Of course, getting the numeric value of an arbitrary character
could be tricky.  I believe the only way to do it (for a potentially
very large set of characters, anyway) would be via character
properties, which weren't supported until sometime in the OpenJade era
(can't recall just when).
