buffer before:
0000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
0010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
Good Luck! ┌∩┐(◣_◢)┌∩┐: Hello World!
buffer after:
0000 48 65 6c 6c 6f 20 57 6f 72 6c 64 21 00 00 00 00 Hello World!....
0010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
Output: Hello World!
