Angular Currency Filter - Symbol  added

Yeah confirmed that this is uglify.

If you build it with the ascii_only=true option then it seems to resolve the problem.

Make sure you have this meta tag.

It seems that when you minify Angular yourself with Uglify.js, and possibly when you combine it with other scripts into one concatenated file and then minify, this issue arises. To solve it you should include the pre-minified version of Angular in your project instead of the development version. I'm not sure if the problem is due to Uglify.js or Angular, but this is how I fixed it.
