Hmm. It looks like this fails on Elixir 1.0.5, which only had \x and not \u. Unless I'm missing something, I don't see anything that's compatible with both 1.0.5 and 1.3.0. @mroth, do you have thoughts about increasing the requirement for this lib to 1.1?

@jeffweiss Thanks for this! I'm surprised there's nothing that's backwards compatible, since this is considered a semantic versioning minor release rather than major. Perhaps check on IRC to be sure?

That said, while maintaining full 1.x compatibility would be ideal, if there is no way to do it short of branching code, then I personally don't have a problem with bumping the versioning requirement, especially since Elixir is primarily early adopters currently, who are more likely to be on a recent-ish version. (In which case, we would want to update the min supported version in the metadata).

@mroth \x{..} still works in 1.3, it just spews a lot of compiler warnings
