Reply To: GREP Bug in Lookaround?

Interesting.

But it’s not the special characters starting with a tilde (~) that’s the problem. I tried using just the Standard Carriage Return special character (~b) in a positive lookahead and lookbehind respectively and they both worked fine.

I’m afraid it’s because the page break is in the previous text frame and InDesign doesn’t regard it as being technically ‘before’ the text. But again, this is only in a positive lookbehind so I’m not sure what causes this.
