Printing these characters in the "Canonical" format gives the output that I expect, while the default format throws me off.

$ echo " " |hexdump                  # Reversed?  
0000000 0a20
0000002

$ echo -n " " |hexdump               # Ok, fair enough.
0000000 0020

$ echo  " " |hexdump -C              # Canonical
00000000  20 0a                      | .|
00000002

With a different string, such as "123" the output is even more confusing:

$ echo  "123" |hexdump
0000000 3231 0a33                    
0000004

The output here does not seem "reversed", but rather shuffled. Would anyone care to explain (briefly) what is going on here?
