DiscoTOC - automatic table of contents

I am using DiscoTOC for a long time, and it works fine with Chinese headings until recent update.

If there are multiple Chinese headings (including no ascii characters) in the post, it will only navigate to the first heading of one level when the navigation item on the right side is clicked. I believe this is because the DiscoTOC generates navigation items with the same id (because the headings are all in Chinese). So, the query selector will only find the first heading.

As a try, I forked the GitHub repo and pushed a little commit as

It seems to work in my site. If it looks good to you team, I can raise a pull request, or this bug need to be fixed in another way.
