That is a bug and not intentional. The attached patch fixes the problem (at
least the LaTeX generation side). With this patch it is possible again to use
the "default" encoding. Unfortunately the display in LyX is wrong: Everything
is treated as latin1. I don't know how that works in LyX 1.4.x (the hebrew
words are displayed with hebrew characters, but not RTL). I'll have a look
and see whether this can be fixed in 1.5. Meanwhile I am going to put in the
attached patch.

You are right, that is exactly the problem.

I'll have a look, see above. The problem is that this "default" encoding does
not fit ver well into the new unicode world, and I am not yet sure how to
integrate it better.

Yes. It is implemented like that because of the limitation of older inputenc
packages.

Yes, we should require a current inputenc version and output each character in
the encoding that it's language demands.
