Non ascii byte string literals broken

[mahkoh]

test.rs:63:42: 63:43 error: byte constant must be ASCII. Use a \xHH escape for a non-ASCII byte: \xdf
test.rs:63     let mut br = BufReader::new(b"Hello, ß World");
                                                    ^

If this is by design then the design is wrong.

Some people seem to think that ASCII isn't an encoding and that byte literal actually means ASCII literal. Restricting byte literals to ASCII makes unnecessary assumptions about the use of byte literals and actively discriminates against people using languages other than English.

And, of course, the bytes! macro doesn't have this bug.

It looks like this and the other shortcomings of byte string literals have been known for at least 4 months and yet neither have byte string literals been fixed nor has the bytes! macro been undeprecated.

An issue such as this belongs on the RFC repo instead of this repository (it is a language change).
