Well, there is also the issue of whether 0 or \0 is used inside the
string.
char str1[]="Ends with zero...0";
char str2[]="Ends here...\0";
String str1 is 19 chars and the last two chars are an ASCII zero (0x30,
IIRC) and a "char zero" (0x00). strlen() would report 18.
String str2 is 14 chars with 2 "char zeros" at the end. strlen() would
report 12.
