Smart Encoding is the easiest way to change non-GSM characters into GSM characters. In the Design step of your campaign, with the help of the toggle under the input area, you can change the non-GSM characters into GSM characters. This helps you to reduce the cost of each message, and you will be in total control of your messages via checking them in the Preview section and testing them.
This guide provides details about:
How to Use Smart Encoding
When you type a non-GSM in the Message Text input area, you will see a warning box below. This warning box will give you information on which characters are special characters that are not supported by GSM encoding.
Moreover, if all those special characters in that message are mapped in Insider’s Smart Encoding, you will see a toggle named Switch to GSM-7.

When you enable the toggle, you will see that the warning box changes into an information box, and the characters in the message will be changed into GSM characters under the preview section. In the example below, “Günaydın :slight_smile:” is mapped to “Günaydin”.
