表情符号序列

Technical/Unicode

由一个或多个Unicode码位按顺序组合，共同表示单个表情符号的字符集合。

While simple emoji like 😀 are a single code point, many emoji are sequences — multiple code points that combine into one visual character. There are several types of emoji sequences:

- **ZWJ sequences**: Characters joined by U+200D (e.g., 👩‍🔬 woman scientist)
- **Keycap sequences**: Digit + VS-16 + U+20E3 (e.g., 1️⃣)
- **Flag sequences**: Regional Indicator pairs (e.g., 🇯🇵)
- **Tag sequences**: Black flag + tags (e.g., 🏴󠁧󠁢󠁥󠁮󠁧󠁿 England)
- **Modifier sequences**: Base emoji + skin tone (e.g., 👋🏾)

Understanding sequences is essential for correctly counting, splitting, and processing emoji in software.
