Does MySQL allow CJK characters to be used in database and table names?
This issue is fixed in MySQL 5.1, by automatically rewriting the names of the corresponding directories and files. For example, if you create a database named 楮 on a server whose operating system does not support CJK in directory names, MySQL creates a directory named @0w@00a5@00ae. which is just a fancy way of encoding E6A5AE — that is, the Unicode hexadecimal representation for the 楮 character. However, if you run a SHOW DATABASES statement, you can see that the database is listed as 楮.
