// In the above string the a-z letters have the same 1-byte values in the GSM character set.
// The '@' character is the 0x00 byte in GSM.
// The curly brace chars are 2-bytes each in GSM -- each beginning with the 0x1B escape char.
// The '.', ' ', and ',' are the same in GSM as us-ascii.

// Let's convert to GSM.

// bdGsm will contain the GSM bytes.
bdGsm := TChilkatBinData.Create(Self);

// Append the string to bdGsm.  The 2nd arg "gsm" tells AppendString to
// convert the incoming string to the gsm byte representation.
success := bdGsm.AppendString(s,'gsm');

// Let's examine what we have in hex:
Memo1.Lines.Add(bdGsm.GetEncoded('hex'));

// The result is:  737570706F7274006368696C6B6174736F66742E636F6D2C201B286162631B29

// Save the GSM bytes to a file.
