That's a good question. U+FFFE and U+FFFF are noncharacters, so they're
not permitted in normal interchange, but I'm not sure whether the UTF-8
sequences that represent them are themselves illegal.
For that matter, if we are excluding the noncharacters U+xxFFFE and
U+xxFFFF, on whatever basis, then we also have to exclude the range
U+FDD0 through U+FDEF. I missed that in my earlier post.
