translate data file with odd Hebrew encoding

I have a binary data file, in a format used by a relatively ancient program, which I am trying to convert into something sane. With the help of a Hex editor I have basically worked out the file format except that it contains Hebrew characters with an odd encoding.

All characters are 8 bits. The "standard" 27 consonants (including "final" consonants) go from hex 80 to 9A. Then there are vowels t开发者_Python百科hat seem to start around hex 9B or so (I'm guessing right after the standard consonants end). Then there are "dotted" consonants that seem to start at hex E0.

If I remember correctly, I think this is some sort of DOS encoding. What encoding is this and what encoding should I translate it to so that a user in Israel will be able to most easily open it in, say, Microsoft Word? Are there any tools that I could use to do the translation?

80 to 9A seem to match the codepoints in the CP862, but I could not find any match for the vowel codepoints. I think what you should do is just make a custom mapping to Unicode and produce the output in UTF-8 or UTF-16LE plain text file. If you add a BOM (Byte-Order-Mark), Notepad and/or Word should be able to read it without issues. I would probably make a small Python script, but it shouldn't be hard in any other language.
