> the `ascii()` built-in function in spark doesn't support Latin-1 Supplement characters which value between [128, 256). Instead, it produces a wrong value, -62 or -61 for all the chars. But the `chr()` built-in function supports value in [0, 256) and normally `ascii` should be the inverse of `chr()`
