Cool idea. The author's AI failed to encode flags for approximately 35% of the world's population. Approximately 3 billion people. At least that's why my AI tells me. India obviously contributes a lot to this. I'm probably salty because my own country's simple (?) flag is also in the "unencodable" group. Lol.

I applaud the author holding aspect ratio as a priority to encode. It's jarring to see an otherwise correct and familiar flag stretched into an incorrect shape when flown or shown.
