Unicode characters don't appear to work

Hello,

I have two issues
I have used your plugin on my website.

First, I use the Vietnamese language to write heading on pages (picture 1) for creating ToC. However, I meet issues like picture 2 and when I click ToC, it doesn't scroll.
Second, I viewed on page source, it showed like <a href="#theoretical-v%C3%A0-empirical-l%C3%BD-thuy%E1%BA%BFt-v%C3%A0-th%E1%BB%B1c-nghi%E1%BB%87m" . I think this link a bad problem for SEO.

I don't know how to fix it. Could you give me some solution?

Do you have an example repository I can look at? I'm currently using kramdown and UTF-8 characters are loading fine for me.

{% capture markdown %}
# Theoretical và-empirical-lý-thuyết-và-thực-nghiệm
{% endcapture %}
{% assign text = markdown | markdownify %}

{% include toc.html html=text class="awesome-toc-class" %}

<ul class="awesome-toc-class">
  <li><a href="#theoretical-và-empirical-lý-thuyết-và-thực-nghiệm">Theoretical và-empirical-lý-thuyết-và-thực-nghiệm</a></li>
</ul>

hello,

Thank your response. I have input files. Please check it

I also using kramdown and UTF-8 characters.

The first time, I write some of heading included Vietnamese (VN) and English (EN) languages. After that, I clicked TOC, it doesn't scroll to VN heading, only EN. Then I try to copy the link address of heading, it looks like <a href="#1-theo-ph%C6%B0%C6%A1ng-ph%C3%A1p-x%C3%A1c-%C4%91%E1%BB%8Bnh-chung" class="nomunge">.

Second time, I combined VN and EN together. For example,

<a href="#theoretical-v%C3%A0-empirical-l%C3%BD-thuy%E1%BA%BFt-v%C3%A0-th%E1%BB%B1c-nghi%E1%BB%87m">

However, I edited content from VN to EN, it runs okay.

I was put toc_pure_liquid.html on _includes/

toc_pure_liquid.txt

and docs.html on _layouts/

docs.txt

Oh man, toc_pure_liquid.txt was the first version that I published years ago. Can you try using the latest version and see if the problem persists?

I update the latest version. However, the issue still shows.

• ToC doesn't scroll if combined VN and EN characters on sentence or just VN characters
• <a href="#"> error characters

Could you please provide some sample content? When I tried decoding the HTML encoded values and used it for my tests, I couldn't replicate your behavior.

Hello,

My blog fork from docs.docker.com, keep all js, css, and their gem. Just put katex js

I check 2 times

• Firstly, I checked the anchor link of heading. it quite good.

• Secondly, I checked the ToC list, it showing some Latin characters combine VN characters.

You can go to my link here.

This doesn't seem to be a problem with the code jekyll-toc is generating. When I disable JS on your website, the TOC links work as intended. This appears to be some JS interfering with the behavior of navigation.
