请教：用c++写的cgi接受到的中文字符为什么是乱码？
int main()
{
char postString[ 1024 ] = "";
int contentLength = 0;
// variables to store user data
string dataString = "";
string name = "";
string email = "";
string content = "";
string getUserIp = "";
string getNowTime = "";
time_t currentTime;
// data was posted
if ( getenv( "CONTENT_LENGTH" ) )
contentLength = atoi( getenv( "CONTENT_LENGTH" ) );
cin.read( postString, contentLength );
dataString = postString;
// search for first '+' character
int charLocation = dataString.find( "+" );
// search for next '+' character
while ( charLocation < string::npos ) {
dataString.replace( charLocation, 1, " " );
charLocation = dataString.find( "+", charLocation + 1 );
} // end while
// find location of tname
int firstStart = dataString.find( "name=" ) + 5;
int endFirst = dataString.find( "&email" );
name = dataString.substr( firstStart,
endFirst - firstStart );
// find location of content
