源码如下：

#define ZEN_MAX_LEN    2056

int FormatKaToZen(char* pDestination ,char* pSource)
{
    char *pTempDest   = pDestination;
    char *pTempSource = pSource;
    char* pTemp = NULL;
    int iTemp = 0;
    char szDestination[ZEN_MAX_LEN] = "";
    char szZen[3] = "";
 
    char szHan[256][3] = {{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},
       {""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},{""},

 for(pTempSource;*pTempSource!='\0';*pTempSource++) 
 {
     iTemp = (int)*pTempSource;
     if(iTemp >= 32 && iTemp <= 126)
     {
         strncpy(szZen,szHan[iTemp],3);
         strcat(szDestination,szZen);
         continue;
     }
     else if(iTemp >= -95 && iTemp <= -33)
     {
         iTemp = iTemp + 256;
         strncpy(szZen,szHan[iTemp],3);
         strcat(szDestination,szZen);
         continue;  
     }
     else
     {
         strncat(szDestination,pTempSource,2);
         pTempSource++;
         continue;
     }

 }

 strcpy(pDestination, szDestination);

 return 0;
}
