I have long used this super elegant array to string converter in 
PostScript...

    /makestring {dup length string dup    % new string of right size
           /NullEncode filter             % make a file out of string
           3 -1 roll
           {1 index exch write} forall
           pop
               } def

Yet it seems to fail in GhostScript, writing all nulls instead.

Does anyone see the problem?
