The Vivox SDK supports UTF-8 encoding for group text communication services and for buddy/presence services.
Note
UTF-8 is backward compatible with printable standard ASCII. If your application uses only printable standard ASCII for text and presence, then no changes are needed.
Arrays that contain text with UTF-8 encoding must have their length specified by the number of bytes, and not by the number of display characters.
For example, the following 9 characters will be sent as a message. They are represented in UTF-8 by an array of 27 bytes. When sending the message, specifying 9 rather than 27 bytes can cause truncation of the message.
