Can not use chinese charactor in alias, it will become '----' when creating the pages folder.

Feature/improvement

The urls is too long and hard to read in HTML report, so I wish use alias, which is more easier to understood like native language - chinese for me. But I found when pass chinese charator to measure.start(url, '中文'), and multiple urls, it will come error like: index out of range when generating HTML report.

When looking into it, I found the error is because the page path is wrong with '----' instead of alias name. When I change alias to English name, it will be good.

Is there any way to use a more readable native charator in alias?

Thanks a lot for your reply.
