Yes. Set Message Type to Unicode.

If you are typing the content in the panel, you can also use Transliterate: with Unicode selected, type in English and press space, and the text converts to the language you chose in the dropdown. Typing “Namaste” with Hindi selected produces नमस्ते.

Two things to keep in mind. A message that mixes text and Unicode is costed entirely as Unicode. And Unicode messages hold far fewer characters per segment than GSM text, so check the segment count before sending a large batch.
