convert method

String convert (List<int> codeUnits, [ int start = 0, int end ])

Converts the UTF-8 codeUnits (a list of unsigned 8-bit integers) to the corresponding string.

Uses the code units from start to, but no including, end. If end is omitted, it defaults to codeUnits.length.

If the codeUnits start with the encoding of a unicodeBomCharacterRune, that character is discarded.


String convert(List<int> codeUnits, [int start = 0, int end]) {
  // Allow the implementation to intercept and specialize based on the type
  // of codeUnits.
  String result = _convertIntercepted(_allowMalformed, codeUnits, start, end);
  if (result != null) {
    return result;

  int length = codeUnits.length;
  RangeError.checkValidRange(start, end, length);
  if (end == null) end = length;
  StringBuffer buffer = new StringBuffer();
  _Utf8Decoder decoder = new _Utf8Decoder(buffer, _allowMalformed);
  decoder.convert(codeUnits, start, end);
  decoder.flush(codeUnits, end);
  return buffer.toString();
