/* This test writes smiling faces and santa clauses out in mostly
 * random order.  In UTF-16, smiling faces can be represented with
 * a single 16-bit value, but santa clauses require a surrogate pair.
 *
 * This test may require special attention in languages that internally
 * represent strings as UTF-16 sequences, such as Java.
