Here's how to use WhatsApp's new font right now
But you don’t have to be signed up to the beta to use it. All you have to do is put three of the grave symbol, which looks like ', before and after the word or phrase that you want to modify. So, you could write '''Look at this weird font I found'''
On iOS, you need to hit the 123 key in the corner and then press and hold the apostrophe to find the grave accent. Android users can find it on the second page of punctuation and symbols.
