 * @assertion String decode(List<int> bytes, {bool allowInvalid})
 * Decodes the ASCII bytes (a list of unsigned 7-bit integers) to the
 * corresponding string.
 * ...
 * If allowInvalid is not provided, it defaults to the value used to create this
 * AsciiCodec.
 * @description Checks that if bytes contains values that are not in the range
 * 0 .. 127, the decoder will eventually throw a FormatException.
