in reply to A serch and replace question

That's because | is special to the regexp engine, and using hex escapes isn't going to disable that. Try this:

$data =~ s/\x0d\x0a[|][|]/||/g; # No /s needed.

    Not true. Using -Mre=debug (output trimmed a bit)
    /a|b/ yields:

    Compiling REx `a|b' 1: BRANCH(4) 2: EXACT <a>(7) 4: BRANCH(7) 5: EXACT <b>(7) 7: END(0) minlen 1

    but /a\x7cb/ yields:
    Compiling REx `a\x7cb' 1: EXACT <a|b>(3) 3: END(0) anchored `a|b' at 0 (checking anchored isall) minlen 3

    (tested w/ 5.005_03, 5.6.0, and 5.8.0)

    I figured using Hex escapes would get around that issue. I guess I was wrong. Thanks.
