WebAssert::addressEquals($page) doesn't work on urls containing utf-8 characters

Scenario Outline: Verify redirects are working correctly 
  When I visit "/de/help/help-topics/puffle-launch/how-do-i-pause-game"                                  
  Then I should be on "/articles/de/FAQ/Tipps-und-Tricks-für-Puffle-Flug" 

Exception:

Current page is "/articles/de/FAQ/Tipps-und-Tricks-f%C3%BCr-Puffle-Flug", but "/articles/de/FAQ/Tipps-und-Tricks-für-Puffle-Flug" expected.

The browser returns an encoded url but is compared with a straight string compare with the un-encoded expected url. As an added issue the Russian language urls were even more impacted due to the php parse_url removing several of the russian characters from the url.

The following code change fixes both issues.

    /**
     * Checks that current session address is equals to provided one.
     *
     * @param string $page
     *
     * @throws ExpectationException
     */
    public function addressEquals($page)
    {
//        $expected = $this->cleanScriptnameFromPath(parse_url($page, PHP_URL_PATH));
//        $actual   = $this->getCurrentUrlPath();

        //Deal correctly with UTF-8 urls
        $encodedPage = preg_replace('%[^:/?#&=\.]+%usDe', 'urlencode(\'$0\')', $page);
        $expected = urldecode($this->cleanScriptnameFromPath(parse_url($encodedPage, PHP_URL_PATH)));
        $actual   = urldecode($this->getCurrentUrlPath());

        if (strcmp($actual,$expected)) {
            $message = sprintf('Current page is "%s", but "%s" expected.', $actual, $expected);
            throw new ExpectationException($message, $this->session);
        }
    }

Start at WebAssert::addressEquals($page), the entry point named in the issue, and inspect how parse_url, getCurrentUrlPath, and URL encoding are currently used. Reproduce the UTF-8 example and verify that address comparisons handle encoded German and Russian URL characters without changing the expected path semantics.
