  for (final char in text.characters) {
    if (_data!.containsKey(char)) {
      result.write(_data![char]);
    } else {
      final codeUnits = char.codeUnits;
      for (final codeUnit in codeUnits) {
        final char = String.fromCharCode(codeUnit);
        result.write(_data![char] ?? char);
      }
    }
