TP0004

Error: invalid character

Example

From the golden case tests/cases/m1/tp0004_invalid_char.tpn:

tp0004_invalid_char.tpn

let x = 1 $ 2
let y = x !

The compiler reports:

tp0004_invalid_char.tpn:1:11: error TP0004: invalid character '$'
tp0004_invalid_char.tpn:2:11: error TP0004: invalid character '!'

The specification lists every code.
