I am not a TeX guru, but as it was explained, here we deal with basic
ascii chars, say "d". I don't see any way to get "d" be something else
that to be simply "d", apart to make "d" active, and define it in such a
way that it will switch to the standard encoding...

But if one do that, think to what will happen to the \def command...
^

And of course calling an input encoding may define the behaviour of not
"standard" chars, but must *not* change the behaviour of standard chars.
