Scryer Prolog does not convert such char buffers to an explicit list representation, they always remain raw bytes. Erlang uses an analogous idea for lists of codes to represent strings. In Scryer Prolog, this pays off especially nicely because the flag double_quotes is set to chars by default; it is one of the few systems in several decades to do this (most other systems currently use the value codes), and therefore this compact internal representation can be easily used in programs, yielding readable strings that can be efficiently processed.
