I just realized that I have bug in my GPS driver. It operates on ASCII data, so [] operator is safe, BUT data can be corrupted (low chance, but non-zero), so it can form valid multibyte character, so my code will panic on it, trying to parse and validate NMEA message. |

It's like the default rule in a lexer, if it ever gets to it then it's an unrecognized character and lexing stops so error handling can proceed.
--edit--
Which I now realize was probably your point.
