When receiving text encoded with the GSM 7-bit alphabet, SMS Studio will convert received Code to corresponding Char. If the Detect Greek option is selected in the connection settings, SMS Studio will try to identify words written entirely in uppercase Greek letters and convert them with the Greek Unicode characters.

When sending text, for detecting if the text can be sent with the GSM 7-bit alphabet without losing information, the Alt 1 characters will be used along with Char. When Force conversion to GSM safe string is requested in the connection settings, all characters from Char, Alt 1 and Alt 2 will be converted to the corresponding Code, while others will be converted to question marks for alphanumeric or dots for punctuation characters.
