My guess is that it is your Windows loading with the wrong charset. Did you set the charset in your html page so that it would force the browser to load it using UTF-8?

It seems to be a problem with how your files is being loaded instead of how they are generated/minified.

The Problem really seems to be the combination of uglify merged files and BOM. My current setup minifies each JS file but doesn't merge them anymore (there's no need to, as the Windows app will store all scripts locally so requests are not a problem). I'm adding the BOM to all of them at the end using the snippet from update 2 of my main post.

My app now successfully certifies and runs flawlessly. Phew...
