2719 ** "test_function" with database handle <db>.  If the second argument is
2720 ** true, then a version of test_function is registered for UTF-8, if the

2722 ** true, a UTF-16be version is available.  Previous versions of
2723 ** test_function are deleted.

2726 **
2727 **   "test_function <enc> <arg>"
2728 **
