It can decode Paul's emojis 🤷
My site isn’t fully compatible because it uses a different approach. While it can decode Paul's emojis, full compatibility isn’t possible since there isn’t a single standard way to encode emojis using zero bytes. Different systems may use different encoding strategies, so universal support isn’t guaranteed.
Interesting. I haven't dug into the actual encoding yet. Regardless, this is a really cool site. Thanks for making it. :)
