When running this spec, I get an encoding compatibility error:

https://github.com/rubinius/rubinius/blob/master/spec/ruby/core/io/gets_spec.rb#L280

results in:

1)
IO#gets transcodes into the IO object's internal encoding, when set ERROR
Encoding::CompatibilityError: undefined conversion for '"\u00FE\u00FF\u0000l\u0000i\u0000n\u0000e"' from UTF-16 to UTF-8

Charless-Mac-Pro:rubinius cremes$ git pull --rebase origin master
From github.com:rubinius/rubinius
 * branch            master     -> FETCH_HEAD
First, rewinding head to replay your work on top of it...
Applying: add basic support for additional IO functions
Applying: add back dup2 function definition
Applying: add convenience methods for errno handling
Applying: add O_CLOEXEC to list for File IO
Applying: add a few more functions like ftruncate to the list
Applying: hack away and rejigger things to get IO booting using mostly FFI calls
