/*
** Usage: add_test_function <db ptr> <utf8> <utf16le> <utf16be>
**
** This function is used to test that SQLite selects the correct user
** function callback when multiple versions (for different text encodings)
** are available.
**
** Calling this routine registers up to three versions of the user function
** "test_function" with database handle <db>.  If the second argument is
** true, then a version of test_function is registered for UTF-8, if the
** third is true, a version is registered for UTF-16le, if the fourth is
** true, a UTF-16be version is available.  Previous versions of
** test_function are deleted.
**
** The user function is implemented by calling the following TCL script:
**
**   "test_function <enc> <arg>"
**
** Where <enc> is one of UTF-8, UTF-16LE or UTF16BE, and <arg> is the
** single argument passed to the SQL function. The value returned by
** the TCL script is used as the return value of the SQL function. It
** is passed to SQLite using UTF-16BE for a UTF-8 test_function(), UTF-8
** for a UTF-16LE test_function(), and UTF-16LE for an implementation that
** prefers UTF-16BE.
