I tossed a legal document at it which was recently of passing interest to me, and it looks like embedded fonts still need some work. I'm not inclined to share a test case from what I have, which relates to a change of name and in any case was not really prepared by anyone especially competent when it comes to PDFs and their content; I tested with the first, facially void, version I was given. But it is possible I'll find more use for this tool, and if a shareable test case does come along then I'll do so. (And heaven knows with <i>this</i> document format, embedded fonts are a total nightmare always, even somehow in programmatic <i>authoring.</i> I'm not criticizing!)<p>On a similar note, a downloadable (single-file HTML or so, although these days some kind of HTTP service is a practical necessity) version would be nice to have. Low pri even from my perspective; it isn't that I spend a lot of time in places with no cell signal, so much as just that tethering on an a la carte plan gets out of hand pretty quick, since applications aren't at all required to honor or even notice the existence of the "data saver" option.<p>This is really neat! Thanks for posting it, I've bookmarked it for later use in the "just need a quick tweak" kind of case. I'll look forward to seeing how it develops!
