Regex for ^K and ^L

[jr8rdt]

I have a txt file which contain ,if I open using linux VI , character ^K and ^L. Using windows excel or txt edit it shows something like a little square shape. I have a perl script running on windows which suppose to filter out these characters using regex. however so far I have not been successful.

I have used below:

first
if ($_ = !~/[0-9a-zA-Z]/){
ignore
}

second

if ($_ = ~/\^/){
ignore
}

third

if ($_ = ~[^\w]){
ignore
}

I think the ^K is from control K. I think....
how to handle this ??

Help!!

If you know it's ctrl-K, then you can use \cK in a regex to match it. If not, use the ord function to print out the numeric equivalent of the character, so you can work out what it is.
