-- Unicode handling

-- Note: this test case is known to fail if the database encoding is
-- EUC_CN, EUC_JP, EUC_KR, or EUC_TW, for lack of any equivalent to
-- U+00A0 (no-break space) in those encodings.  However, testing with
-- plain ASCII data would be rather useless, so we must live with that.
