          Description

          MariaDB [test]> SELECT CONCAT(CONVERT('pi' USING ucs2),PI()) AS bad, CONCAT(CONVERT('pi' USING ucs2),CONCAT(PI())) AS good;
+----------------+------------+
| bad            | good       |
+----------------+------------+
| pi㌮ㄴㄵ㤳     | pi3.141593 |
+----------------+------------+
1 row in set (0.00 sec)

          The first column with PI() produces a wrong value.
          The second column with CONCAT(PI()) returns a good value.

          The first column should be fixed to return the same value with the second one.
