NULL終端バイト文字列（NTBS）の値がゼロバイト（終端のNULL文字）が続くゼロ以外のバイトのシーケンスです。バイト文字列の各バイトは、いくつかの文字セットの1文字をエンコードします。たとえば、文字配列{'\x63','\x61','\x74','\0'}はASCIIエンコーディングで文字列を保持して"cat"NTBSです.

Original:

A null-terminated byte string (NTBS) is a 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.
