MySQL 8.0 Reference Manual
MySQL 8.0 Release Notes
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.
