以null结尾的多字节的字符串（NTMBS），或“多字节字符串”，是一个序列的非零字节一个字节的值为零（终止空字符）.
Original:
A null-terminated multibyte string (NTMBS), or "multibyte string", is a sequence of nonzero bytes followed by a byte with value zero (the terminating null character).

。存储在字符串中的每个字符占用一个字节以上。用来表示一个多字节字符串中的字符的编码是特定于语言环境的：它可能是UTF-8，GB18030，EUC-JP，SHIFT-JIS，等。例如，char数组{'\xe4','\xbd','\xa0','\xe5','\xa5','\xbd','\0'}是容纳字符串的NTMBS，"你好"在UTF-8多字节编码的前三个字节编码字符你，在接下来的三个字节编码字符好。在GB18030编码是相同的字符串char数组{'\xc4', '\xe3', '\xba', '\xc3', '\0'}，其中每两个字符被编码为两个字节的序列.
Original:
Each character stored in the string may occupy more than one byte. The encoding used to represent characters in a multibyte character string is locale-specific: it may be UTF-8, GB18030, EUC-JP, Shift-JIS, etc. For example, the char array {'\xe4','\xbd','\xa0','\xe5','\xa5','\xbd','\0'} is an NTMBS holding the string "你好" in UTF-8 multibyte encoding: the first three bytes encode the character 你, the next three bytes encode the character 好. The same string encoded in GB18030 is the char array {'\xc4', '\xe3', '\xba', '\xc3', '\0'}, where each of the two characters is encoded as a two-byte sequence.

。在一些多字节编码的，任何给定的多字节字符序列可能代表不同的字符，根据前一个字节序列，被称为“移位序列”。这种编码被称为依赖状态：当前的移动状态的知识来解释每个字符。一个NTMBS是唯一有效的，如果它的开始和结束的初始位移状态：如果移位序列，相应的不印字序列之前应终止空字符。作为这种编码，可以是7位的JIS，BOCU-1和SCSU .
Original:
In some multibyte encodings, any given multibyte character sequence may represent different characters depending on the previous byte sequences, known as "shift sequences". Such encodings are known as state-dependent: knowledge of the current shift state is required to interpret each character. An NTMBS is only valid if it begins and ends in the initial shift state: if a shift sequence was used, the corresponding unshift sequence has to be present before the terminating null character. Examples of such encodings are the 7-bit JIS, BOCU-1 and SCSU.

。一个多字节字符串是布局兼容的空终止字节的字符串（非关税壁垒），可以存储，复制，并探讨了使用同样的设施，除了计算的字符数。如果是在正确的语言环境中，I / O功能，同时处理多字节字符串。多字节字符串可以被转换成宽字符串的std::codecvt成员函数，std::wstring_convert，或以下的语言环境相关的转换函数：。
Original:
A multibyte character string is layout-compatible with null-terminated byte string (NTBS), that is, can be stored, copied, and examined using the same facilities, except for calculating the number of characters. If the correct locale is in effect, I/O functions also handle multibyte strings. Multibyte strings can be converted to and from wide strings using the std::codecvt member functions, std::wstring_convert, or the following locale-dependent conversion functions:
