The Unicode General Category of the characters can tell you that.
I can prepare a compact table if you need.

I prefer the latter.  Moreover, there was the discussion of
monospace fonts on the OpenType list last week.  Seems like
according to the OpenType spec, a monospace font should have all
the widths equal, no zero width allowed.  Combining characters
can get their width zeroed using OpenType tables.  There were
suggestions to change this behavior though.
