I believe it was added in 7.1, requested by Bernd Raichle.  Since then
it has been heavily modified.  I suspect that -- for the original
purpuse -- the current combination of TCX plus -8bit is a better match
than locales.

Formally (from my p.o.v. at least) encTeX has only been recently added
to web2c.  encTeX is disabled by default.

The "default" is only affected by setting the locale.  I'm not sure I
really want to pile on another set of flags modifying the behaviour.
Especially since I doubt we could reach agreement on what they'd have
to be/do.

I suspect by fiddling with the locale.
