标签序列

使用特殊标签字符（U+E0020至U+E007E）表示地区旗帜（如英格兰、苏格兰、威尔士）的表情符号旗帜序列。

While country flags use Regional Indicator pairs, subdivision flags (states, provinces, regions) use a different mechanism: tag sequences. These start with the black flag emoji (🏴 U+1F3F4), followed by tag characters spelling out an ISO 3166-2 code, and end with the cancel tag (U+E007F).

For example, 🏴󠁧󠁢󠁥󠁮󠁧󠁿 (England) is: 🏴 + tag-g + tag-b + tag-e + tag-n + tag-g + cancel tag. The tag characters are invisible and exist solely for this encoding purpose.

Currently only three subdivision flags are in widespread use: England (gbeng), Scotland (gbsct), and Wales (gbwls), though the mechanism supports any ISO 3166-2 code.
