执行字符集Execution Character Set
此内容通常指“执行字符集”。This content often refers to the "execution character set." 执行字符集不一定与用于编写 C 程序的源字符集相同。The execution character set is not necessarily the same as the source character set used for writing C programs. 执行字符集包含源字符集中的所有字符以及 null 字符、换行符、退格符、水平制表符、垂直制表符、回车和转义序列。The execution character set includes all characters in the source character set as well as the null character, newline character, backspace, horizontal tab, vertical tab, carriage return, and escape sequences. 源和执行字符集在其他实现中可能不同。The source and execution character sets may differ in other implementations.
