Appendix F GSM Alphabet
Standard SMS can contain 160 characters. However, the characters typed must be part of the
so-called 7-bit default alphabet as specified by GSM 3.38. As shown in the table below, this alphabet
contains all ASCII characters and some accented characters.
For example, u umlaut (ü) and e with grave (è) are in this set. Using any character not in this set will
force the SMS to be a Unicode SMS, in which case the length of the SMS will be limited to 70
characters.
Note that the following characters count as two characters: { } [ ] ~ | \ and the Euro
symbol €. As you can see in the table below, this is because the codes for these characters must be
prefaced by the escape code (0x1B).
The table below shows the 7-bit default alphabet as specified by GSM 03.38. The corresponding
ISO-8859-1 decimal codes are shown in the rightmost column. Note that the euro sign (€) is also
included.
