There’s ‘%graft-hooks’ in (guix build graft).  One could add a hook that
would do nothing except for SBCL packages; for SBCL packages, it would
to the UCS-4 rewriting “somehow”.

The other option, which might be easier, would be to arrange to not use
UCS-4 in the first place, by choosing a bytevector data type for string
literals known to contain a store reference.  It can be done if we know
where those references come from—e.g., they’re introduced by
‘substitute*’ on the source.

I hope this makes sense!
