/*
 * This file implements a very simple iconv.
 * Its purpose is to allow ASCII clients to communicate with Microsoft servers
 * that encode their metadata in Unicode (UCS-2).
 *
 * The conversion algorithm relies on the fact that UCS-2 shares codepoints
 * between 0 and 255 with ISO-8859-1.  To create UCS-2, we add a high byte
 * whose value is zero.  To create ISO-8859-1, we strip the high byte.
 *
 * If we receive an input character whose value is greater than 255, we return an
 * out-of-range error.  The caller (tds_iconv) should emit an error message.
