I saw the link with \K myself, but it does the opposite - instead of disregarding everything BEFORE it, it disregards everything AFTER it. Had it not been for the way it matches U as well, I would have put it down to a forgotten/undocumented feature of PCRE.
Also, the following example seems to suggest that it doesn't just look ahead, it looks through the ENTIRE pattern again:
//echo -ag $regex(aU,/(\K)a/)
Thrull: I was looping through \a \b \c etc etc to save every character they match. I noticed that \K on it's own just matched U, which I thought was odd so I experimented a bit
Is anyone able to test on another application also using the updated PCRE? If it does the same there, I'll file a bug report with the creators.
