I'm sorry to have been so laconic in my last message. Basically,
what I need to do is to translate Unicode text into entity references,
or, if you like, Unicode characters into ASCII characters. In other
words, if my input is Псалми Давидови, I want my output to be
(In case the input didn't survive transmission, it was "the Psalms of
David" in Bulgarian.) The input characters will normally be from
Unicode block 0400-04FF, but may also be from elsewhere, e.g.
1F00-1FFF. The platform I'm using is Windows 2000, about which
I have no choice, it's what is in use here. (This is actually the origin
of my request, because until now, using a less "advanced"
operating system, I used to be able to effect these transformations
without any difficulty.)
Thank you for your forbearance; I hope this is now a more sensible
