Twilio Message - Emojis are replaced with "?" in the actual message

Question

I am using twilio to send sms messages through my Java Application.

And when I am sending emojis, emoji is being replaced with ? in the actual message I am getting.

I wasn't able to figure out what is the issue.

Any inputs about this error could be really helpful.

I read in twilio website that emoji's delivery is not guarateed. But I tested with multiple carriers. And I didn't get the emoji in not even one. Even if anyone aware of the list of carriers that it could support, it will be great.

Emoji support has not been standardised across carriers, as a result we cannot guarantee support for Emoji across all of them. We will do the best we can to ensure the emoji in your message is delivered to your mobile carrier, but if they don't understand that emoji, they will usually replace it with gibberish.

Chances are that you will see some carriers show emoji and some not.
