Description:
I use UTF8 ("SET NAMES UTF8").
I have a name Ñ (N-tilde).
The ExtractValue() function calls this name a "syntax error".

How to repeat:
mysql> CREATE PROCEDURE p2 ()
    ->      BEGIN
    ->        DECLARE p LONGTEXT CHARACTER SET UTF8 DEFAULT '<Ñ><r>A</r></Ñ>';
    ->        SELECT EXTRACTVALUE(p,'/Ñ/r');
    ->      END//
Query OK, 0 rows affected (0.01 sec)

mysql>
mysql> CALL p2()//
ERROR 1105 (HY000): XPATH syntax error: 'Ñ/r'

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 5.1.5-alpha-debug

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
