\ //~ ERROR: unknown start of token: \

fn main() {}
Improve char escaping in lexer messages Currently ', " and \ are escaped as \', \" and \\ respectively. This leads to confusing messages such as `error: unknown start of token: \\` when encountering a single backslash. Fix by emitting printable ASCII characters directly. This will still escape \r, \n, \t and Unicode characters. Fixes #47902 2018-02-01 08:15:38 +11:00			`\ //~ ERROR: unknown start of token: \`
