I notice in the proposed tr18 update at
http://unicode.org/reports/tr18/proposed.html#Compatibility_Properties
That they've again diddled the \p{word} property for \w; they've
added \p{Join_Control} to the set of what goes into that
particular derived property. That's just these two code points:
U+0200C -- GC=Cf SC=Inherited ZERO WIDTH NON-JOINER
U+0200D -- GC=Cf SC=Inherited ZERO WIDTH JOINER
This makes sense because those are two (non-Mark!) Grapheme_Extend characters,
which may in theory be needed for composing identifiers in certain scripts
(Indic, perhaps).
