Yes, Unicode encoding is used to send any character that is not in the default GSM character table. Unicode is useful to support languages such as Arabic. Maximum length allowed for unicode content is 70 characters, while text messages will allow up to 160 characters.

To send Unicode message, add the "type=unicode" parameter for HTTP users or set DCS=8 for SMPP users.
