I think this may be more common than you think. Certainly on Mac OS
X, the standard text engine maps sequences with combining marks to
precomposed characters where possible. For example:
î (U+00EE, Latin small letter i with circumflex)
î (U+0069, Latin small letter i; U+0302, combining circumflex accent)
look identical to me, with the circumflex correctly placed and no dot
on the i. Do these look different to you?
(P.S. In programs that use nonstandard text engines that don't
handle combining marks correctly, these sequences *do* look
different...but that's a separate issue.)
