2259 **
2260 ** Calling this routine registers the collation sequence "test_collate"
2261 ** with database handle <db>. The second argument must be a list of three
2262 ** boolean values. If the first is true, then a version of test_collate is
2263 ** registered for UTF-8, if the second is true, a version is registered for
2264 ** UTF-16le, if the third is true, a UTF-16be version is available.
