/* Tests conversion from Unicode to HZ-GB-2312 (bug 367026)
 *
 * Notes:
 * HZ-GB-2312 is a 7-bit encoding of the GB2312 simplified Chinese character
 * set. It uses the escape sequences "~{" to mark the start of GB encoded text
 * and "~}" to mark the end.
 *
 * See http://www.ietf.org/rfc/rfc1843.txt
