Invalid character error only in IE browser and only for production environment

[kumkanillam]

Due to some newer feature usage(I am not sure is it in my app folder or from addon) in my project, uglify.js is not working for minification, so I uninstalled ember-cli-uglify and included ember-cli-babili reference (http://rwjblue.com/2017/04/21/ember-cli-targets/).

Here comes the issue,
In group-utils.js file,there is const DIACRITICS = { 'Ａ':'A' } 840 characters defined here .
In develpment environment,its working fine since key is in single quotes const DIACRITICS = { 'Ａ':'A' }
In production environment, it's minified as const DIACRITICS = { Ａ:'A' }. this throws Invalid character error in IE-11 browser.

Interesting. A new way Internet Explorer breaks the web. Yay!

I supposed that we can replace the non-utf8 chars by their escaped versions and babili will work. Let me see if I can find the source from where I took this initially.
