Early Java versions represented Unicode characters using the 16-bit char data type. This design made sense at the time, because all Unicode characters had values less than 65,535 (0xFFFF) and could be represented in 16 bits. Later, however, Unicode increased the maximum value to 1,114,111 ...
Table – 7: Scripts of Southeast Asia in Unicode What is the size of char in C? The size of char is usually 1 byte in C. The size of char in Java is 2 bytes. It is an unsigned integral, 16-bit value, used for representing UTF-16 code-units. Why is the size of a char, 2...

那么问题来了,如果用了utf8mb3编码的mysql数据库,在插入一些4字节长的字符时就会报错(形如:"java.sql.SQLException: Incorrect string value: '\xF0\x9F\x94\x91\xE6\x9D...' for column 'core_data' at row 1" 的错误),后文会介绍如何在Java中过滤掉这些字符。

新兴编程语言 Rust 的设计很好,其 String 是 UTF-8 编码,其 char 是 UCS-4 编码,并且 char 指的是unicode scalar value,这个术语指去掉 high surrogate 和 low surrogate 这 2048 个 code points 后剩下的 code points,这个设计非常完美,完全避开了 surrogate pair—— surrogate pair 表达的字符就用 0x10000...
The first (high) surrogate is a 16-bit code value in the range U+D800 to U+DBFF. The second (low) surrogate is a 16-bit code value in the range U+DC00 to U+DFFF.For example 𓅡 (U+13161 EGYPTIAN HIEROGLYPH G029) is a character in the Supplementary Multilingual Plane. The UTF...
