RI

Technical/Unicode

成对使用时可组合成国旗表情符号的Unicode字符（U+1F1E6至U+1F1FF），依据ISO 3166-1 alpha-2代码对应各国国旗。

Flag emoji use a clever encoding system: 26 Regional Indicator symbols correspond to letters A-Z. When two are paired to form a valid ISO 3166-1 country code, platforms render them as that country's flag.

For example, 🇰 (U+1F1F0, RI K) + 🇷 (U+1F1F7, RI R) = 🇰🇷 (South Korea). This means no new code points are needed when countries change — only the ISO mapping and platform rendering need updating.

There are 258 flag sequences defined in Unicode. On platforms that don't support flag rendering (like Windows), the two Regional Indicator letters are shown as letter pairs instead.
