统一码

Technical/Unicode

为所有书写系统和符号集（包括表情符号）中的每个字符分配唯一编号的通用字符编码标准。

Unicode is the foundation of modern text computing. Before Unicode, competing encoding standards (ASCII, ISO 8859, Shift JIS, etc.) made international text exchange error-prone. Unicode provides a single, consistent mapping from numbers to characters.

The standard defines over 154,000 characters spanning 168 scripts. Emoji are allocated primarily in the Supplementary Multilingual Plane (Plane 1), starting around U+1F600. The Unicode Consortium releases new versions annually, each potentially adding new emoji.

Unicode only defines *what* each code point means — the actual byte representation depends on the encoding form used (UTF-8, UTF-16, or UTF-32).
