I am trying to use moment-with-langs.min.js, but I got the following error message from js-test-driver. error loading file: /test/thirdParty/moment/moment.min.js:7: Uncaught SyntaxError: Invalid regular expression: /^?erven$|^?vn$/: Nothing to repeat. I think the problem is July (červenec), looks like encoding issue. I have converted moment-with-langs.min.js to UTF-8 and ANSI, same error. So I am thinking it might be some setting in jstestdriver? thanks.

moment-with-langs.min.js is from https://github.com/moment/moment/releases/tag/2.5.1 inside min folder.
