Yes, I've read those, but I'm not so sure they fit for Hebrew.  In
Hebrew there is usually no collision - simple composition is sufficient
in most cases.  However, in some cases there might be collision - two
characters or accent have pixels on the same place - these cases can to
be resolved by rules to prevent overstriking, but those rules must be
applied only when there is a collision.

Would it be possible to modify compose-string so it would signal
overstriking?
