I absolutely disagree that these two problems are analogous at all:
Separating surrogate pairs is (a) UTF-16 specific and (b) leaves the
result uninterpretable. Gumming up a grapheme cluster is more like
an off-by-one error in inserting a character: the output is garbled
but not garbage.

One time I called in to the central system and started working on a big
thick 'sed' and 'awk' heavy duty data bashing script. One of the geologists
came by, looked over my shoulder and said 'Oh, that happens to me too.
Try hanging up and phoning in again.' --Beverly Erlebacher
