I was wondering why this was never used for an simpler autocorrect, but i guess that's why.
Also perhaps someone more educated on LLMs could tell me; this wouldn't always be consistent right? Like "once upon a time _____" wouldn't always output the same thing, yes? If so even copying and pasting in your own system using the correct font could change the content.
It's not a bug, it's a feature - a DRM. Your content can now be consumed, but cannot be copied or modified - all without external tools, as long as you embed that TTF somehow.
Which kind of reminds me of a PDF invoices I got from my electricity provider. It looked and printed perfectly fine, but used weird codepoint mapping which resulted in complete garbage when trying to copy any text from it. Fun times, especially when pasting account number to a banking app.
