Description:
There is currently no way to specify a Unicode character escape sequence for use in string literals. The strange thing is that it is possible to specify that a string is to be encoded in Unicode UTF8, but it is not possible to actually use any non-latin character inside that string.

How to repeat:
N.A.

Suggested fix:
I would like to have the possibility to specify Unicode characters as is for instance possible in HTML 水 or Java "\u6c34" to allow SQL statements like:

INSERT INTO myunicodetable(mycolumn) 
    VALUES(_utf8'use the chinese character \u6c34');

It should be possible to use in any place where an SQL statement can be used, including the command line client and stored procedures.

We have public worklog for this, http://forge.mysql.com/worklog/task.php?id=3529

The worklog can no longer be found.

The closest there is now is this:
mysql> SELECT X'E6B0B4';
+-----------+
| X'E6B0B4' |
+-----------+
| 水        |
+-----------+
1 row in set (0.00 sec)
