lint creating a &str (or String) from invalid UTF-8 bytes

[llogiq]

This is also undefined behavior (according to the rust book), calling std::str::from_utf8_unchecked(..) on something which is not UTF-8.

[Manishearth]

I don't see why someone would ever use from_unchecked on a literal?

[llogiq]

Perhaps within a macro?

[John-Steidley]

Perhaps because of a refactor. Perhaps because they passed the literal into a function.
