Overview

1 2 Len
107 Len Characters

String does NOT have a corresponding Erlang representation, but is an optimization for sending lists of bytes (integer in the range 0-255) more efficiently over the distribution. Since the Length field is an unsigned 2 byte integer (big endian), implementations must make sure that lists longer than 65535 elements are encoded as LIST_EXT.

(see STRING_EXT)
