/**
 * @assertion Uri.dataFromBytes(
 *  List<int> bytes, {
 *  mimeType: "application/octet-stream",
 *  Map<String, String> parameters,
 *  percentEncoded: false
 *  })
 * Creates a data: URI containing an encoding of bytes.
 *
 * Defaults to Base64 encoding the bytes, but if percentEncoded is true, the
 * bytes will instead be percent encoded (any non-ASCII or
 * non-valid-ASCII-character byte is replaced by a percent encoding).
 *
 * To read the bytes back, use UriData.contentAsBytes.
 *
 * It defaults to having the mime-type application/octet-stream. The mimeType
 * and parameters are added to the created URI. If any of these contain
 * characters that are not allowed in the data URI, the character is
 * percent-escaped. If the character is non-ASCII, it is first UTF-8 encoded
 * and then the bytes are percent encoded.
 * @description Checks that this constructor creates an expected Uri. Test
 * valid mimeType parameter specified
 * @issue 28592
 * @author sgrekhov@unipro.ru
