Custom checkboxes and radiobuttons used to work many years ago, but 
they’re broken for years – Hans blames Adobe for that.

Your example works well in Apple Preview, Acrobat Pro 9 (2010), Skim, 
TeXshop, Safari, File Viewer. All of these use Apple’s PDF library, 
except the old Acrobat.

Foxit Reader, Master PDF Editor, Opera, Firefox never show the custom 
icons but the default checkmark (Firefox a cross).
PDF Studio 2019 doesn’t even that but shows a "4".
PDF.js in Atom doesn’t support forms (but show the red icon).

(I tested on MacOS 10.14.)
