When signing a PDF file with jsignpdf, with no visible signature, it adds two font files:
Helvetica
ZapfDingbats
My system is Windows 11.
Are these fonts necessary for an unvisible signature? I think, removing them could make the signed file smaller and more opensource-compliant, since these are proprietary fonts.
