LoadError in Airbrussh::Console#utf8_supported?

[mike-stewart]

Using airbrussh 1.1.0 (w/ capistrano 3.6.0 and ruby 2.1.7), I intermittently get a LoadError printing certain non-ASCII text. Sometimes it prints OK, sometimes it blows up.

This is the backtrace for a string containing the Unicode character "𝄞" (U+1D11E):

LoadError: dlopen(enc/trans/single_byte.so, 9): image not found - enc/trans/single_byte.so

I fixed it by also rescueing LoadError here: https://github.com/mattbrictson/airbrussh/blob/master/lib/airbrussh/console.rb#L84

Any ideas on what could be going wrong here, or would you be open to a PR to add a rescue @mattbrictson?

Thanks for the report!

My hunch is that this is a problem with your Ruby installation. I'd rather not add a rescue unless this problem is widespread. Can you see if there is a fix for your Ruby?

I found this, maybe it will help: http://stackoverflow.com/questions/13277729/ruby-loaderror-enc-trans-single-byte

I looked at that earlier and tried the suggested solution of ensuring everything in ~/.rvm (I use RVM on OS X) was readable by my user. Also tried reinstalling my ruby. No dice.

I'll dig in some more and post here if I can find a solution.
