Usually, a Chinese will occupy two bytes of space. In many languages, a Chinese character is 2 characters long.In C #, however, the Chinese characters contained in string are only one character long. This leads to a lot of times when you use String.

Most buffer overflow problems in C can be traced directly to the standard C library. The worst culprits are problematic string operations (strcpy, Strcat, sprintf, and get) that do not perform self-variable checks. In general, strict rules such as
