 * @assertion const AsciiCodec({bool allowInvalid: false})
 * Instantiates a new AsciiCodec.
 *
 * If allowInvalid is true, the decode method and the converter returned by
 * decoder will default to allowing invalid values. If allowing invalid values,
 * the values will be decoded into the Unicode Replacement character (U+FFFD).
 * If not, an exception will be thrown. Calls to the decode method can choose to
 * override this default.
 * @description Checks that this constructor, called without parameters,
 * instantiates a new AsciiCodec with decoder which doesn't allow invalid
