Invalid file source (API)

[Pavel_M]

When upload a file on the server via GET request get the error "Invalid file sourse" if URL contains national characters, example: http://hf5.l2central.info/images/f/f3/Навык_Воителя_-_Сопротивление_Отрицательным_Эффектам.jpg

Try to html encode that url. http://meyerweb.com/eric/tools/dencoder/

Tried, does not work: Invalid file source.

There are several errors triggered by this URL. First thing is that PHP's default filter_var for URL (FILTER_VALIDATE_URL) doesn't recognize this URL as valid, so the G\is_url() function must be improved. I ended doing something like this:

    // This will tell if the string is an URL
    function is_url($string) {
        // Internal PHP system
        if(filter_var($string, FILTER_VALIDATE_URL)) { // Note: This doesn't validate any non-alphanumeric URL
            return true;
        }
        // Test if it has foreign chars
        if(strlen($string) !== strlen(utf8_encode($string))) {
            $parsed_url = parse_url($string);
            if(count($parsed_url) < 2) { // At least scheme and host
                return false;
            }
            $schemes = ['http', 'https', 'ftp', 'ftps', 'mailto', 'news', 'irc', 'gopher', 'nntp', 'feed', 'telnet', 'mms', 'rtsp', 'svn', 'tel', 'fax', 'xmpp'];
            if(!in_array(strtolower($parsed_url['scheme']), $schemes)) { // Must be a valid scheme
                return false;
            }
            if(!array_key_exists('host', $parsed_url)) { // Host must be there
                return false;
            }
            // At this point this thing looks like an URL
            return true;
        }
        return false;
    }

With that the thing validates as URL but then the problem is, again, the Cyrillic (actually multibyte) chars. I'm still working on it and most likely this will get patched for the next version.
