According to the POD, this is a "feature". Here is a quote from the POD:
"undef is returned if the susbstring length is one char or less."
I'm not sure why the author decided on this behavior because it seems reasonable to return a substring of length 1.
There is a patch which can be adapted to enable this behavior. Refer to:
