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

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // Demonstrates how to convert a string to the GSM character set byte representation.

  final 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.
  final bdGsm = CkBinData();

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

  // Let's examine what we have in hex:
  print(bdGsm.getEncoded('hex'));

  // The result is:  737570706F7274006368696C6B6174736F66742E636F6D2C201B286162631B29

  // Save the GSM bytes to a file.
  bdGsm.writeFile('qa_output/gsm.txt');
