Here is another example of Sencha-CMD building for production causing issues with unicode characters.

https://github.com/jsheely/extreact-...-unicode-error

If you build this project in dev. It works fine. if you npm run build you'll see a console.log error

HTML Code:
 [E] Ext.ux.rating.Picker.applyGlyphs(): Expected 2 characters for "glyphs" not "☆★".
If anyone has a work around for this it would be appreciated.
