So you basically have files that mix different encodings of Hebrew
characters, is that right?
If so, I would suggest indeed to set up the display table, but not as
you did it in older Emacsen. What you need is to map those 8-bit
bytes to the Unicode codepoints of the corresponding Hebrew
characters. That is, let the slot of eight-bit character #xA0, which
is represented in Emacs as #x3FFFA0, be set in the display table to
#x5d0 (the Unicode codepoint of Aleph). Then you will see Aleph when
the file has #xA0, provided that you read the file with no-conversion.

If you set up the display table as I describe above, both X and text
terminals will work. For text terminals, you will need to set
terminal-coding-system to some Hebrew capable encoding that these
terminals support. For GUI displays, you need a font to be installed
that is capable of displaying Hebrew characters.

There should be no problem in using the same display table set up as
above on all types of terminals.

The locale environment shouldn't have any effect on that. All it does
is set defaults for certain coding-systems. You will want to override
those defaults anyway, e.g. for using no-conversion when visiting
these files. I don't see anything else that might interfere, do you?

You could write your own coding-system, but I think display tables are
easier.
