There appear to be two ways to handle hex codes -- one is the one that you are using:

\x1B

The other is the method used by Mr. Muskrat:

\x{263a}

If you're using 'wide' hex digits (as I assume is the case since you're talking about four digits in this example) then you probably need to use the \x{...} approach.

If you'll tell us a little more about what you're doing, we might be able to move beyond a single substitution. Unless that's all you need, in which case this appears to work:

s/\x{0024}/$delimiter/

And you don't need to make it part of a character class

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).
Want more info? How to link or How to display code and escape characters are good places to start.
