    It does not, really.  And this is not relevant to a discussion about
XeTeX.


It is, since it may determine how dependent I and others
may be on xetex still being around.  If the replacement
can't do what you want then you can't do the switch.

However I very much like being able to use teckit mappings,
so I really wish xetex will stay around.

If you find the right hook, you can do the same eg with regular
expressions. it will be possible to do even more then with teckit but
the correct hooks must be found.

Of course -- I have written transliterators for use outside the
TeX world -- but it's very convenient to have such a thing
ready-made! :-)
