Ran both snippets on little endian and big endian machines.
In all (four) cases the results were the same.
Did you observe something different ?
Details:
(gdb) b main
Breakpoint 1 at 0x8048350: file hex-char.c, line 5.
(gdb) r
Starting program: ~niyer/trials/hex-char
Breakpoint 1, main (argc=1, argv=0xbfe72a34) at hex-char.c:5
5 unsigned char uc[] = "\xFF";
(gdb) n
6 return 0;
(gdb) p uc
$1 = "ÿ"
(gdb) p /x uc
$2 = {0xff, 0x0}
