Pour convertir les caractères « sépciaux d’une URL en caractères (exemple { = %7B = Ascii(123)) :

 #define ARRAYSIZE 29  
 String cCarSpec[ARRAYSIZE] = {"%20", "%22", "%27", "%23", "%25", "%26",  
                "%28", "%29", "%2B", "%2C", "%2E", "%2F",  
                "%3A", "%3B", "%3C", "%3D", "%3E", "%3F",  
                "%40", "%5B", "%5C", "%5D", "%5E", "%60",  
                "%7B", "%7C", "%7D", "%7E", "%21"  
                };  
 int nConv[ARRAYSIZE] = {32, 34, 39, 35, 37, 38,  
             40, 41, 43, 44, 46, 47,  
             58, 59, 60, 61, 62, 63,  
             64, 91, 92, 93, 94, 96,  
             123, 124, 125, 126, 33  
             };  
 String transCar(String sChaine)  
 {  
  for (int i = 0; i < ARRAYSIZE; i++)  
  { char cCar = nConv[i];  
   String sCar = String(cCar);  
   sChaine.replace(cCarSpec[i], sCar);  
  }  
  return sChaine;  
 }  

La conversion étant effectuée par exemple : new_ssid = transCar(new_ssid);
