Ok, but I must declare the pointer as a const?

I see...
Yes. Constness is needed to give enough freedom for COW String implementations.
If you want to write those chars, you could use StringBuffer:
String x...
StringBuffer xb(x); //Clears x, takes the content
char *x = xb;
// do what you want, investigate StringBuffer interface to learn more
x = xb; // put it back, clears xb
Of course, another option is to simply copy String to separate buffer, however StringBuffer guarantees minimal copying.. (if possible, it performs none).
