* Ensure the test runner decodes files as UTF-8

Before this change, the `document.charset` of the HTML test files would be 'windows-1252' when accessed through the `file://` protocol, resulting in issues with library or test files containing non-ASCII symbols.

This patch ensures tests still run correctly when files contain non-ASCII symbols.

* Ensure ASCII-safety of source code

Presently we are supporting unicode characters of Russian extension characters manually in JS.
This should be changed in future by setting right flags.
Previous PR: #2223

Surprisingly, we need not set unicode characters of upper case '\u0414\u041E\u0411'. This woks fine.

* Configure Russian extension character доб as a valid one while parsing the numbers

* Escaping non ascii characters for better standardization.

* Added generated RU test data file. This is why travis test are failing at: https://travis-ci.org/googlei18n/libphonenumber/builds/407078226

* Removing manual support of encoded versions as it is already taken care in RegEx flags. Updated based on new review comments.
