#![feature(unicode)]

[spicavigo]

With rustc (1.0.0-beta.3 (5241bf9c3 2015-04-25) (built 2015-04-25))

I just created a dependency with bincode = "*" in my code. Now cargo build is saying

/Users/XXX/.cargo/registry/src/github.com-1ecc6299db9ec823/bincode-0.1.2/src/lib.rs:6:1: 6:21 error: unstable feature

/Users/XXX/.cargo/registry/src/github.com-1ecc6299db9ec823/bincode-0.1.2/src/lib.rs:6 #![feature(unicode)]

note: this feature may not be used in the beta release channel
error: aborting due to previous error
Could not compile bincode.

Fixed in efa1afd

Run cargo update -p bincode to get the beta-compatible version.

This unfortunately adds an allocation to the middle of emitting chars, but hopefully that doesn't happen very often.

I'll change it back once the unicode crate stabilizes.
