Hi there,
I found this module is quite interesting and easy to catch up.

Currently, I got into situation where I need to implement some kind of searching, but the search engine is not fully support utf8. So, it's may good for user to be able to convert ❤️ => :heart: and back, :heart: => ❤️

I'm also done a prototype for these implementation. My repo: liemle3893@985fe95

It's cool if we can add this feature.

Regards.
