On twitter, I have mine showing perfectly. Don't use the code, use the emoji...I wanted to use my emoji domain on Twitter bio but it wouldn't accept the puny code.
It sometimes has problems if there are a bunch (or possibly more than one) links in the post. Meaning that it won't post the tweet. Otherwise, it works good for me.Okay, thanks @CJ6 appreciated, sure I tried this method but'l I'll try the way above, thank you.
