This works great until you try to put it into brackets...
s/(\x{0024})/$delimiter/gm;

    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
