8-bit char to Hex representation
<p>I'm trying to convert 8 bit <code>char</code> into hex view which looks like this:</p>

<pre><code>00 03 80 45 E5 93 00 18 02 72 3B 90 88 64 11 00 
45 FF 00 36 00 FF 45 00 00 34 7B FE 40 00 40 02
</code></pre>

<p>But some characters contain negative values which makes a larger hex value of more than 2 digits. how would i get each one as represented above?</p>
