Perhaps what is meant by the original request would be satisfied by
the property:
Default_Ignorable_Code_Point
defined in
http://www.unicode.org/Public/3.2-Update/DerivedCoreProperties-3.2.0.t
xt
These are essentially characters that have no visible glyphs and no
advance width, but may have a different effect on the rendering of the
text in which they are found (depending on context).
