No matter what language you’ve written your form in, you can make sure that it’s recognized by web browsers. All you have to do is specify the language in your form’s settings.
To set a form’s language, open it from Forms and go to Settings > General settings. In the Language drop-down menu, choose the language your form is written in.
Remember to save your form when you’re done. Your browser should now recognize that your form is written in the language you’ve chosen
