+## Fix
+### IE8 Invalid Character
+IE8 doesn't support some unescaped Unicode character and need to quote keys in object literals
+You need some configurations for [Uglifier](https://github.com/lautis/uglifier) to do the work.
+Add to your `config/environments/production.rb`
+
+       require 'uglifier'
+       config.assets.js_compressor = Uglifier.new(output: {ascii_only: true, quote_keys: true})

 ## Version
 From `v2.1.0` on, `select2-rails`'s version will match the version of `Select2` it uses.
 
 The last number of the version is the patch version specific to the gem. For example, for a version of the form `2.x.y`, `2.x` is the release of `Select2` we should be compatible with, and y is the patch version specific to the gem (ie. to resolve any gem-specific issues that crop up).
