Styling radio buttons

I am creating an interactive PDF for a client. Now I have a layout with, for example, radio buttons with text yes/no. I have styled the buttons so that they contain the text yes/no. When I export the PDF, it looks good in preview and in some web browsers (Safari), but in PDF reader and Acrobat I just get circles with a check mark in them. So people don't know whether it is yes/no.

I have already searched a lot and saw this script (https://answers.acrobatusers.com/Highlighted-Fields-forms-switched-opening-PDF-Form-created-How-this-q21870.aspx) and I have added it. However, this does not have the desired result.

How can I let the client use my formatted PDF as it is formatted? Isn't this the whole point of the form functionality in InDesign that this works well?
