Google captcha as multilingual.

[Kumail Raza]

Recently I have requirement to change the language of google captcha to arabic.

I figure out that Google Captcha has the multilingual feature, but I tried different ways but no proper solution unless

a tweak came to my mind (but I believe not the right solution)

Normally : http://www.google.com/recaptcha/api.js?render=explicit

/* PLEASE DO NOT COPY AND PASTE THIS CODE. */
(function() {
    if (!window['___grecaptcha_cfg']) {
        window['___grecaptcha_cfg'] = {};
    };
    if (!window['___grecaptcha_cfg']['render']) {
        window['___grecaptcha_cfg']['render'] = 'explicit';
    };
    window['__google_recaptcha_client'] = true;
    var po = document.createElement('script');
    po.type = 'text/javascript';
    po.async = true;
    po.src = 'https://www.gstatic.com/recaptcha/api2/r20170126104253/recaptcha__en.js';

    var elem = document.querySelector('script[nonce]');
    var nonce = elem && elem.getAttribute('nonce');
    if (nonce) {
        po.setAttribute('nonce', nonce);
    }
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(po, s);
})();

I try  : http://www.google.com/recaptcha/api.js?render=explicit 

thought of 

    po.src = 'https://www.gstatic.com/recaptcha/api2/r20170126104253/recaptcha__ar.js';

might it change 'en' to 'ar' but it always 'en'. I would like to know the best approach. Can you provide the solution?

As per https://developers.google.com/recaptcha/docs/display#config try using http://www.google.com/recaptcha/api.js?render=explicit&hl=ar

Also, a hidden gem... if you explicitly render the reCaptcha widget, you can pass `hl` with the parameters object. It will download the right script and render in that language. It's not documented as a parameter, but does work.
