Object->string takes an optional "printer" argument.  The default is write,
but you can also use display.

scheme@(guile-user)> (help object->string)
`object->string' is a procedure in the (guile) module.

 -- Scheme Procedure: object->string obj [printer]
     Return a Scheme string obtained by printing OBJ.  Printing
     function can be specified by the optional second argument PRINTER
     (default: `write').

 
scheme@(guile-user)> (object->string "\n")
$1 = "\"\\n\""
scheme@(guile-user)> (object->string "\n" display)
$2 = "\n"
