Lua4z was built using the IBM-1047 code page but the lexer and parser
have been patched to tolerate IBM-037
http://lua4z.com/doc/manual/using.md.html#Square_brackets.
Unfortunately, output is printed in IBM-1047 which is why the square
brackets are garbled. I could fix this but you need to specify your
codepage with a setting in LUACONF.
Although Lua4z tolerates IBM-037 I would highly recommend switching to
IBM-1047 if you can. Most people use IBM-037 due to inertia and don't
even use square brakets or caret characters.
You will soon run into issues with Lua4z if you want to use one of the
JSON libraries with IBM-037.

I had to change the brackets to x'AD' X'BD', the same as I use for java.
The for i = 1, count do a[i] = i * i end statement fixed the problem.

This suggestion is probably unrelated to the actual issue, but I see the odd
characters ÝC¨ in your note, which I think should display as square brackets.
If your terminal emulator is currently set to use code page
37 (or similar), you might try code page 1047.
