Bash: how to get a byte from a number?

Question

I want to convert a number to its byte equivalent. Currently I do this:

echo $((0xe0)) | hexdump -c

And I get this output:

0000000   2   2   4  \n

What I want to get is:

0000000 e0

How should I do?

But `echo $((0xe0))` will output `224`, which is a String, consisting of 3 characters: 2,2 and 4. It's not the number 224, nor a character with the hexadecimal value 224. — Konerak, May 30 '12 at 11:36
Too bad there is no answer that actually accepts the input from STDIN (or using a pipe) then. — Konerak, May 30 '12 at 21:58

You can try:

printf '\xe0'

echo -ne '\xe0'
