Take a look in perlre. \D is the non-digit class, but maybe that isn't what you want. You'd better look up which control chars you can encounter there and use an custom class. Something like:
s/^[\001-\017\s]{0,2}//; # char 0 to 15 (and whitespace)
While we're at it, why not simplify it to a one-liner?
perl -pe 's/^[\001-\017\s]{0,2}//' infile.txt >outfile.txt
See perlrun for nifty options... the 'i' is also very useful.

Update
Listen to blackmateria. Of course you use the :cntrl: POSIX class.. much more convenient.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
