Bernhard, you must have missed my most recent reply to Christian above. My
error was *not* in attempting to «reconvert» a hexadecimal representation to
yet another hexadecimal, but rather in simply mistaking a decimal
representation (2204, which represents the same number as the hexdecimal
089c), found as I explicitly noted, on p 1 of the Unicode table, as being
that of the Unicode glyph (∄) in question, whereas it codes for an entirely
different glyph. Very kind, in any event, of both you and Christian to
attempt to explain the misteries of hexadecimal representation....

Henri
