The "Stéréo" case wasn't actually expected to match - the problem was that
due to the bug it was matching sometimes, depending on exactly what happened
when PCRE backtracked off the start of the buffer. Other times it would just
crash.

The current definition of \X is pretty much fine for western alphabets - all
the complicated stuff in the grapheme cluster definition is mainly for indic
and east asian alphabets and the like.
