Test failure - RSpec::Support::Differ#diff copes with encoded strings

[liam-m]

While trying to set up my system to implement #252, I encountered a test failure:

Run options: include {:focus=>true}

All examples were filtered out; ignoring {:focus=>true}

This occurred after cloning this repo and running rake, as well as when following the steps in rspec-dev:

git clone git://github.com/rspec/rspec-dev.git
cd rspec-dev
bundle install --binstubs
bin/rake setup
bin/rake # runs tests in every repository

This is on OS X 10.11.2 with Ruby 2.1.7 (using rvm)

We'll need some more details to replicate this, as it works locally for the rest of us (and on travis), whats your locale etc?

[liam-m]

I'm happy to provide any information I can but I'm not sure what would help. How can I find the locale? This is my Language & Region:

[JonRowe]

can you gist your environment? (You can find this with printenv)

I removed some things that I thought may be sensitive but I don't think it was anything relevant

[fables-tales]

My totally unfounded reckon is that this is an RVM bug. I've seen untraceable issues like this with my install before and it's one of the main reasons that I switched to chruby. Unless anyone else reports this I think we should close as it doesn't seem to be a widespread issue. Thoughts?

[JonRowe]

I use rvm without issues but I've not yet had a chance to try @liam-m's env...

[liam-m]

I tried running the tests with my system Ruby and all tests passed, so it's looking increasingly likely it's an RVM bug. Feel free to close if you don't want to do any extra investigation
