Ok here is every character available on the calculators:
If you want to post the top 10 symbols you would want the most and a possible token to use for its representation on calc.
I already have all letters, numbers, period, question mark, exclamation, comma, single quote, opening parenthesis, closing parenthesis, colon, and negative sign so please do not post these again.
Hex character / TI on-calc token
1. 05h (right pointing arrow) / > token
2. 3Bh (semi colon)/ i (complex) token
3. F2h (money sign) / pi symbol token
