ruby 2.1.3p242 (2014-09-19 revision 47630) [x86_64-linux]
-e:1:in `split': invalid byte sequence in UTF-8 (ArgumentError)
	from -e:1:in `<main>'

ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]
-e:1:in `split': invalid multibyte character: /\xFF/ (RegexpError)
	from -e:1:in `<main>'

This is leaking implementation details and so I think is a bug as such.
The bug was discovered thanks to https://github.com/rubyspec/rubyspec/blob/archive/core/string/split_spec.rb#L16-L23.

string.c: proper exception

• string.c (rb_str_split_m): raise ArgumentError at broken string
  not RegexpError, as Regexp is not involved in.
