Re: [perlre] 4-digit hex code in regexp? How to specify?

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/` [download] And you don't need to make it part of a character class	[reply] [d/l] [select]
