The coding-system-for-read is hebrew-iso-8bit.

Yes, that's my problem, I have Hebrew in #xE0-#xFA (iso-8859-8)
but I have other 8 bit bytes (most of them are graphic shapes
from the cp862 set).

Just a typo, it should be 154.

All my data files are 8bit bytes, so for me it is always, character =
byte (at least externally).

I attach a tar.bz2 file with 3 files:
1. lit1 - the sample file.
2. lit1-tty.png - how it should show on text terminal.
3. lit1-x.png   - how it should show on X.

I can do it if I read the file with the iso-latin-1 coding-system
and change the display table to show the Hebrew glyphs for the Hebrew
[#xE0-#xFA] bytes. But in this way it is not Hebrew characters (e.g.
for the new bidi display). I want it the other way around, to read it
with hebrew-iso-8bit and to to tweak the display table to show all
the bytes not belonging to the Hebrew set.

I had similar problem a long time ago. In 2001 you suggested to use
the following code:

  (make-coding-system
      'hebrew-iso-8bit 2 ?8
      "ISO 2022 based 8-bit encoding for Hebrew (MIME:ISO-8859-8)"
      '(ascii hebrew-iso8859-8 nil nil
              nil ascii-eol ascii-cntl nil nil nil nil nil t)
      '((safe-charsets ascii hebrew-iso8859-8 eight-bit-control)
        (mime-charset . iso-8859-8)))

May be I can define a new coding system that will have bytes #x80-#xFF
as legal characters and be recognized as Hebrew variant.

Ehud.
