With a quick grep through the two programs, my guess is that 'toEnum'
is being specialised at type Char to an internal function 'chr', and
that the implementation of 'chr' only converts Ints up to some limit
like 128.  (Both programs apply toEnum to Ints in the range 128<c<256.)

If this is the case, it should be easy to fix.
