Appendix: GSM 7-bit Default Alphabet Table (with Character Codes of ISO 8859 Latin 1)
The following table lists all characters and their decimal and hexadecimal codes as defined in the "GSM 7-bit default alphabet" text coding scheme. The corresponding character codes defined in ISO 8859 Latin 1 are also provided in the table for ease of reference. The GSM 7-bit default alphabet consists of 128 characters totally and each character is represented by 7 bits. 10 extra characters are defined in the GSM 7-bit default alphabet extension table and they have to be represented through an escape mechanism using the escape character (0x1B). The 10 extra characters are:
Form feed
Caret / circumflex
Left curly bracket
Right curly bracket
Backslash
Left square bracket
Tilde
Right square bracket
Vertical bar
Euro sign
The codes of the 10 characters above begin with 0x1B (i.e. the escape character), which indicates they are escaped sequences. For example, the code of the Euro sign is 0x1B65.
If the receiving entity (for example, a mobile phone) does not understand the escape mechanism, the escape character should be shown as the space character on the display device.
