Detect encoding of bytedata

Implementation

  /// detect list
  List<Encoding>? orders,

  /// return utf8 when has U+FEFF BOM, either return utf16
  bool utf8BOM = true,
}) {

    return utf8BOM ? utf8 : utf16;
  }
  if (hasUtf16LeBom(bytes)) {
    return utf16;
  }
  if (hasUtf32beBom(bytes)) {
    return utf32;
  }

  for (Encoding encoding in (orders ?? defaultDetectOrder)) {
    if (canDecode(encoding, bytes)) {
      return encoding;
    }
  }

  return defaultEncoding;
