Demonstrates how to convert a string to the GSM character set. For more information about the GSM character set, see GSM Character Set

Note: This example requires Chilkat v9.5.0.79 or greater. Support for the GSM character set was added in v9.5.0.79.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// Demonstrates how to convert a string to the GSM character set byte representation.

var s = "support@chilkatsoft.com, {abc}";

// 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.
var bdGsm = new CkBinData();

// 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:
console.log(bdGsm.GetEncoded("hex"));

// The result is:  737570706F7274006368696C6B6174736F66742E636F6D2C201B286162631B29

// Save the GSM bytes to a file.
success = bdGsm.WriteFile("qa_output/gsm.txt");
