But then, how would you distinguish between the valid UTF-16 replacement
used to represent an invalid character, and a valid UTF-16 character
representing itself?  I'm sorry, but the value of a 1-to-1 round trip
mapping outweighs the convenience of displaying a glyph that looks the
same but causes ambiguous round trip conversions.
