/**
 * @assertion const Utf8Codec({bool allowMalformed: false})
 * Instantiates a new Utf8Codec.
 *
 * The optional allowMalformed argument defines how decoder (and decode) deal
 * with invalid or unterminated character sequences.
 *
 * If it is true (and not overridden at the method invocation) decode and the
 * decoder replace invalid (or unterminated) octet sequences with the Unicode
 * Replacement character U+FFFD (�). Otherwise they throw a FormatException.
 * @description Checks that this constructor creates valid Utf8Codec
