"It looks the same" is completely different than having been directly extracted from digital source.
If the digital source is the only thing that can be copyrighted, then you have to prove the digital source is what was used inappropriately. If you can't prove that, either because it didn't happen or because there's no technological way to prove it, then you can't prove copyright infringement.
Ages ago, I consulted on a case where a converted font was included in a product --- it was even simpler than https://luc.devroye.org/kinch.html since no transformations were applied --- just had to figure out which version of which font editor was used to open up the font file and then which settings were used to re-generate the font in the new format used for the infringing product.
I'm not saying it's never possible in any case, just that in cases where it's not you can't prove infringement.
