Ankush,

Unless I'm mistaken, you want to convert a string of hex
values represented in ASCII into its corresponding ASCII
string.

This should do just that:
$ echo "41 50 52 49 4C 20 46 4f 4f 4c 0a"| xxd -r -p
APRIL FOOL

However, this does NOT result in the text "APRIL FOOL"
on your specified input string of:
"41 65 72 74 3A 20 49 6E 74 65 72 66 61 63 65"

In order to convert your string, we'll need to figure out its
encoding format.
