Converting Int to String without conversion in ASCII

I am trying to convert a int variable into a string one, but the String() function is converting it to ASCII. So if I want to convert 255 to "255" I am getting "66" instead. I read that itoa should be able to do that, but when I try itoa(255,buffer,10); it still gives me 66.

Works for me:

void setup() {
  char buffer[4];
  Serial.begin(115200);
  itoa(255,buffer,10);
  Serial.println(buffer);
}

void loop() {
}

Must be a problem in the code you didn't post.
