Ruby < 2.1.0 Compatibility

[joshuabach]

Your gemspece specifies compatibility with any Ruby >= 1.9.3, but this library is not, in fact, compatible with Ruby 1.9.3, because of this line in lib/unicode/display_width/index.rb:

require 'rubygems/util'
[...]

The file rubygems/util.rb is not included in the rubygems bundled with the 1.9.3 stdlib, but was only added somewhere between 2.0.0 and 2.1.0.

As noted in #17, this require is not actually required and the simplest solution would be to remove the rubygems dependency alltogether. Otherwise, you should increase the version constraint in your gemspec.

Thanks!

I've just released v1.3.3 which removes this line and replaces it with direct zlib based implementation.

Please re-open if problem persists.
