utf-8

(edited) I am reading a JSON file that includes some UTF-8 characters that are encoded like this: "\uf36b". I am trying to write a RegExp to convert this to an HTML entity that looks like "🍫". This displays the character correctly in my html page.

I haven't been able to correctly display the character that should be associated with "\uf36b", especially when in a longer sentence that also includes other text.

How can I write a regexp that replaces strings like "\uf4d6" and "\uf36b" but leaves other text alone?

Example:

var str = "I need \uf36b #chocolate";

This should be converted to:

I need &#x1F36B; #chocolate;
