Unlike literally any other platform or OS, Windows never had flag emojis, and that always irked me a little bit. Having to guess what flag someone else is trying to send by just two letters isn't a great user experience, you know. And I always just kinda sighed at it, helplessly.
But not this time... Last week, the absence of flag emojis in Windows has triggered me like never before, and I've spent 14+ hours hyperfocused on the task of bringing flag emojis to Windows (while keeping all its original emojis). I experimented with fonts, and made one that works. And you can download it too!
TL;DR: Install this font for all users, restart your PC, and enjoy! (more details here)
