Convert HTML Entities - My problem

My response from another thread:

This bug is a little bizarre. I’m guessing you copy/pasted the entities from the test descriptions, which “escape” the entities in a rather unusual way, and as a result, you get this:

'&​amp;' === '&' //false
'&​amp;'.length //6
'&​amp;'.split(''); //["&", "​", "a", "m", "p", ";"]
'&​amp;'.codePointAt(1).toString(16); //"200b"

That codepoint, U+200B , is a zero-width space . It’s one of a few zero-width characters in Unicode that are very useful for specialized applications but can also poop on your parade when you least expect it.

Delete all those zero-width spaces and your code should pass the test cases with no problems.

It looks like the test descriptions have already been fixed on the master branch of the fCC repo, but the newest version hasn’t been pushed to production yet.
