Indeed, but some are less unsafe than others. You can't use U+FFEF, because some process might actually filter out noncharacters. You can't use U+FFFD, because some process might generate a special glyph for it (SC UniPad does). And the moment you settle on some hollow rectangle or square as your example, someone will point out that it doesn't match the black square or whatever that appears on *his* system. -Doug Ewell Fullerton, California
