What are the random non-hexadecimal characters in a sequence of hexadecimals? : <p>I have a sequence of characters from an rdf file I opened with python.</p>

<pre><code>...\x00\x08\x00\x00\x80\xdc\xc0\x00\t{\x00\x00\xa3p\x00\xe2\xc00...
</code></pre>

<p>I understand that these are hexadecimals. However, there are some that do not compute as hexadecimals, such as xa3p. What are they and why are they here. And what is \t? Tab?</p>
