MySQL 8.4 Release Notes
12.13.3 复杂字符集的多字节字符支持
If you want to add support for a new character set named MYSET
that includes multibyte characters, you must use multibyte character functions in the ctype-
source file in the MYSET
.cstrings
directory.
The existing character sets provide the best documentation and examples to show how these functions are implemented. Look at the ctype-*.c
files in the strings
directory, such as the files for the euc_kr
, gb2312
, gbk
, sjis
, and ujis
character sets. Take a look at the MY_CHARSET_HANDLER
structures to see how they are used. See also the CHARSET_INFO.txt
file in the strings
directory for additional information.
