It looks like github-slugger could be used to solve this issue too.

I also encountered this problem， try custom renderer

  const renderer = new marked.Renderer();
  renderer.heading = (text, level, raw) => {
    const id = raw.toLowerCase().replace(/[^a-zA-Z0-9\u4e00-\u9fa5]+/g, '-');
    return `<h${level} id=${id}>${text}</h${level}>\n`;
  };

  const result = marked(src, { renderer });
