Whoops, overzealous pasting.  That is, "e\u0308", which composes 
to "ë".  A grapheme cluster seems to represent one printed 
character: "...a horizontally segmentable unit of text, 
consisting of some grapheme base (which may consist of a Korean 
syllable) together with any number of nonspacing marks applied to 
it."

Is that about right?
