Search by unicode
Was finding myself a few times trying to enter Unicode (Hex) value into the search field, but don't get any results. Would be great if this was possible to reverse-lookup icons like that, especially when debugging.

I am not sure how Algolia Search works with regards to field indexing, but could not see anything in the code that made me believe I could create a pull request - probably Algolia Dashboard thing?
