You missing the point that most of my files are not "word-processor"
(or HTML/XML) files but are data file that are either read as ISO-8859-8
or no-conversion (binary) encoding.
Now, some of them has DOS Hebrew (#x80-9A) and graphic characters in
them, in ADDITION to UNIX Hebrew (#xE0-FA). I still want to see it as
Hebrew characters (so I can read it) but with a distinction between the
2 Hebrew types, I want to know the 8-bit encoding, it matters.
When I visit a file literally (i.e. no conversion) I still want to see
the Hebrew (and DOS graphic) characters as Hebrew and graphics, not as
an octal representation.
So I have to use a display table, and I want it to work for both text
terminals and X (or other windowed system - Mac, MS - which I myself
don't use).

What I want is just a subset of this in my display table, so bytes in
the range #xB0-#xDF will be shown as is on text terminal and as the
CP862 glyphs on X (I am willing to have different display tables for
each case, I don't use text terminal and X on the same Emacs instance).
I know how to do it when the locale environment is set to "en_GB".
Can you instruct me how to do this when the locale environment is set
to "he_IL" ?
Just as curiosity, some times I get files where the Hebrew is encoded
as the lower Latin letters and Aleph is represented by @ (this is
known as old-code and it is still used by some companies, even though
in is some other applications already use UTF-8 XML files).
Do you have a way to display it as Hebrew without a display table ?
Ehud.
