 * @assertion UriData.fromString(
 *  String content, {
 *  String mimeType,
 *  Encoding encoding,
 *  Map<String, String> parameters,
 *  bool base64: false
 *  })
 * Creates a data: URI containing the content string.
 * Equivalent to new Uri.dataFromString(...).data, but may be more efficient if
 * the uri itself isn't used.
 * @description Checks that if encoding is not provided and parameters has a
 * charset entry, that name is looked up using Encoding.getByName, and if the
 * lookup returns an encoding, that encoding is used to convert content to bytes
