Null-terminated byte strings
From cppreference.com
A null-terminated byte string (NTBS) is a possibly empty sequence of nonzero bytes followed by a byte with value zero (the terminating null character). Each byte in a byte string encodes one character of some character set. For example, the character array {'\x63', '\x61', '\x74', '\0'} is an NTBS holding the string "cat" in ASCII encoding.
