What languages are supported by Twilio SMS?

Twilio SMS messages can be sent using the Unicode character set.

If you make a request to Twilio’s API with a Unicode message body, Twilio can deliver the message to the carrier. If the carrier sends a Unicode message to Twilio, Twilio can correctly deliver that message to your application.

It’s important to keep in mind that not all carriers or devices have support for Unicode, or the fonts required to display Unicode characters.
