Hello,

Running the tests on v4.1.1 reveals one failure:

I have reproduced this easily. I applied the following patch to test the output:

The results looks like this:

[indutny]

It is about Chinese characters and latest OS X (I think):

1. This is what we write in hex: 'e1848ae185a7e186ab', which is three chars: ᄊ, ᅧ, and ᆫ. Combined together they are 쎤
2. OS X reports it back as 'ec8ea4', which is 쎤

I think we should just fix the test and make it pass a single char. Thoughts?

If it is a problem with the OS X then let's use a different name just for that environment alone.

This is a duplicate of #2165, my proposed fix is at #3007.
