there is no way to add "Character Limit" from the admin panel. Tomorrow during our support hours we'll provide you solution. If 100 characters limit will be for all text area's in your form, it will be "ok" for you?
Have a nice weekend!

I'm sorry, but for the moment we can propose you to set limit for all text areas. At this week we plan to launch new version of Forms and this feature will be added for text inputs and text areas
