theMessageText写入日志文件为乱码？该怎么解决

theMessageText写入日志文件为乱码？

C/C++ code


 retcode=SQLExecDirect (hstmt,(SQLCHAR *)sqlUpdate, SQL_NTS);
 if((retcode != SQL_SUCCESS) && (retcode != SQL_SUCCESS_WITH_INFO))
 { 
   SQLGetDiagRec(SQL_HANDLE_STMT,hstmt,1,(SQLCHAR*)theDiagState,&theNativeState,(SQLCHAR*)theMessageText,100,&iOutputNo);
 writeLogInfo(theMessageText); //写入日志文件；
 }

经过测试给函数writeLogInfo()传入其他参数写入到日志文件中显示都正确，唯独传入theMessageText写入的就是乱码,这是怎么回事？

看看你的theMessageText是什么编码，是不是UTF-8编码?
