import 'package:chilkat/chilkat.dart';

void main() {

  final charset = 'not_used';

  // Unicode escape all chars using \uHHHH
  sb.setString(str);
  sb.encode('unicode-escape-all', charset);
  print(sb.getAsString());
  // Output is \u0062\u00f4\u006e

  // Unicode escape only 8bit chars using \uHHHH
  sb.setString(str);
  sb.encode('unicode-escape-8bit', charset);
  print(sb.getAsString());
  // Output is b\u00f4n

  // To use uppercase hex chars (A-F), add "-upper" to the encoding name
  sb.setString(str);
  sb.encode('unicode-escape-all-upper', charset);

  // Output is \u0062\u00F4\u006E

  // Unicode escape all chars using \u{HHHH}
  sb.setString(str);
  sb.encode('unicode-escape-all-curly-upper', charset);
  print(sb.getAsString());
  // Output is \u{0062}\u{00F4}\u{006E}
