We have a build script which we are using but it doesn't accept special characters. I noticed it breaking on your project. The character was a ’ apostrophe and it's just in a comment. I have replaced that with a regular one.
This sounds like a flaw in your build script. Typographically correct apostrophes shouldn't cause problems, as the encoding of JS files should be assumed to be UTF-8 or UTF-16.
