can't support emoji and  

[Deeeeex]

I found that emoji like ":smile:" can't displayed normally in my website When I change the Markdown engine to hexo-renderer-markdown-it I found that emoji shows well but checklist like "- [x]"can't be displayed.

markedjs does not supports emoji. We have to implement it by ourselves if we want to use emoji with hexo-renderer-marked.

Or you can try 3rd party plugins like: https://github.com/theme-next/hexo-filter-emoji
