* AI thought me this.
*
* Explanation:
* * Each letter in a 2-letter country code is converted to a Regional
* Indicator Symbol, which together form the emoji flag.
* * 'A'.charCodeAt(0) is 65, and '🇦' starts at 0x1F1E6 → offset of 127397
* (0x1F1A5).
* * So 'A' → '🇦', 'B' → '🇧', etc.
*
* The flags are the combination of those emojis making the country code like
* Portugal -> PT.
