The Font Generator: Copy and paste fonts that actually survive the paste

Hey Product Hunt! I built The Font Generator after getting annoyed that fancy-text sites hand you 100 styles and never mention that half of them turn into empty boxes on Android, get stripped by Instagram, or get read out letter by letter by screen readers. So for every style it notes where it actually works, which letters are missing (italic 'h' and several script capitals live outside the main Unicode block, so naive converters break), and how much of your character limit it costs, since most of these characters count double. It's a static site with no backend: no account, nothing uploaded, your text never leaves the browser. There are also A to Z letter pages, a signature generator, text-to-logo and a font-pairing tool. I'd love to know: which app or platform should I test compatibility on next?
