Decode from Binary Encoding and Append String

Demonstrates how to decode from a binary encoding (base64, hex, url, etc.) and then append the decoded string to a Chilkat StringBuilder object.

Note: This example uses the new DecodeAndAppend method added in Chilkat v9.5.0.87.

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // We have the string "MÆRSK" in two forms:

  // This is the URL encoding of the windows-1252 representation.
  final nameWindows1252UrlEncoded = 'M%C6RSK';

  // This is the URL encoding of the utf-8 representation.
  final nameUtf8UrlEncoded = 'M%C3%86RSK';

  // Note that the result of loading a string into a string object 
  // is the same if we correctly specify the underlying charset encoding.
  // In the above example, we have the same string, but in different charset encodings
  // subsequently URL encoded.
  final sb1 = CkStringBuilder();
  sb1.decodeAndAppend(nameWindows1252UrlEncoded, 'url', 'windows-1252');

  final sb2 = CkStringBuilder();
  sb2.decodeAndAppend(nameUtf8UrlEncoded, 'url', 'utf-8');

  // sb1 and sb2 both hold the same string.
  final bEqual = sb1.contentsEqualSb(sb2, true);
  print('bEqual = $bEqual');

  // We can see the string is "MÆRSK" in both cases.
  print(sb1.getAsString());
  print(sb2.getAsString());
}
