this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Parse a string representing a character literal into its final form. Rather than just accepting/rejecting a given literal, unescapes it as well. Can take any slice prefixed by a character escape. Returns the character and the number of characters consumed.
