Well, here is the actual loop which does the lowering for you:
for (i=0; i<len; i++) {
ch = tolower((unsigned char)*c);
*c++ = ch;
}
return (s);
It is using the std c-function tolower()
man tolower tells me
NAME
toupper, tolower - convert letter to upper or lower case
RETURN VALUE
The value returned is that of the converted letter, or c if
the conversion was not possible.
So I take it all weird characters are just left alone and returned to
you, as is.
