How to replace extended ASCII characters in C#?
<p>I am trying to replace non-printable characters ie extended ASCII characters from a HUGE string. </p>

<pre><code>foreach (string line in File.ReadLines(txtfileName.Text))
            {
                MessageBox.Show( Regex.Replace(line,
              @"\p{Cc}",
              a =&gt; string.Format("[{0:X2}]", " ")
            )); ;

            }
</code></pre>

<p>this doesnt seem to be working.</p>

<p>EX:
AAÂAA should be converted to AA AA</p>
