It is assumed to do just that -- and I don't see any problem
in the C code.  

There could be a problem at the lisp level though as
overlay-arrow-string is nil unless it has been set explicitly by some
package.  Perhaps it would make sense to initialize the global value
of overlay-arrow-string to "=>" which most packages want?

Can you produce a simple, self-contained test case demonstrating the
problem?

Then we can see if it works to set overlay-arrow-string's
global value to "=>".
