Explanation.

• A lot of apps use HTML entities instead of ASCII characters which when pasted to composer are not decoded.

Proposal

1. There is a good library that does this for us https://www.npmjs.com/package/html-entities.
2. But this contains a lot of code which we don't really need.
3. So my idea is to extract the List of chars from https://github.com/mdevils/html-entities/blob/master/src/named-references.ts.
4. Then using the regexp match we can convert them easily without using the library.
5. This function will be an extended version of underscore the _.unscape https://github.com/jashkenas/underscore/blob/master/modules/_createEscaper.js

@parasharrajat already fixed some examples in this GH #4169
Let's make sure we address any/all relevant ones so we don't end up with a ton of small issues/fixes (which eat away at valuable resources)

I'm OOO next week so reassigning this - looks like @mallenexpensify might have a steer on whether we need to move this one to engineering

Seems like a reasonable formatting change! Sending to eng for another set of eyes.
