Actually got it to work. Here's the code to do so
field_resources = PDResources.new
field_resources.put(COSName.get_pdf_name('ZaDb'),
PDType1Font::ZAPF_DINGBATS)
on_appearance_stream.cos_object.set_item(COSName::RESOURCES,
field_resources)
...
I've also added an explicit off appearance.
Thanks for the help

Like this:
PDPageContentStream cs = new PDPageContentStream(renderer.document,
appearanceStream);
but try the hard way first, as you almost got it to work.
re your file, I looked at
Root/AcroForm/Fields/[8]/AP/N/Yes
That one misses the resource directory with the font entry for ZaDB -
although maybe it works because ZaDb is in the default resources.
Another thing missing is the "Off" entry.
