JSON option to force unicode

I'm using PHP version > 5.5, but I need Unicode output. Native json_encode($data) returns Unicode output until I add JSON_UNESCAPED_UNICODE. But Nette doesn't let me choice and force non-Unicode output.

Yeah, I can simply workaround here by extending this class. IMHO this function should has one more parameter or some settings if we already have JSON class.

My point is – output shouldn't be dependend on PHP version but on options instead.

Silly example:

/**
	 * Returns the JSON representation of a value.
	 * @param  mixed
	 * @param  int  accepts Json::PRETTY
	 * @return string
	 */
	public static function encode($value, $options = 0, $FORCE_UNICODE)
	{
		if($FORCE_UNICODE)
		{
			$flags = 0;
		}
		else
		{
			$flags = PHP_VERSION_ID >= 50400 ? (JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES | ($options & self::PRETTY ? JSON_PRETTY_PRINT : 0)) : 0;
		}

		if (PHP_VERSION_ID < 50500) {
			$json = Callback::invokeSafe('json_encode', array($value, $flags), function($message) { // needed to receive 'recursion detected' error
				throw new JsonException($message);
			});
		} else {
			$json = json_encode($value, $flags);
		}

		if ($error = json_last_error()) {
			$message = isset(static::$messages[$error]) ? static::$messages[$error]
				: (PHP_VERSION_ID >= 50500 ? json_last_error_msg() : 'Unknown error');
			throw new JsonException($message, $error);
		}

		$json = str_replace(array("\xe2\x80\xa8", "\xe2\x80\xa9"), array('\u2028', '\u2029'), $json);
		return $json;
	}
