trying to match non ascii chars

Hi,

 

I have  bit of  problem with  transparent squid service.  When people tries
to send binary data through squid, the log files naturally doesn't like it
very much.  A sample of such an log file entry:

 

1308293915.456      0 client.host.name NONE/400 3660
[<FF><92>i<8F>>^]^D<D5>^N<9F>?<EF><EA>[<BB>y<81>'4/^<F1><92>k<FA>I<FB><A3>${
b<8B><D2><AE>o^S %87)d%B8%5B%F6W%A2$%5C - NONE/- text/html

 

I am trying to write  perl regex to skip lines containing these characters,
but I'm not having too much success:

 

while (<>) {

  chomp($_);

  if ($_ =~ s/[\t\n\r\f\a\e\cK]//g) {

    next;

  } else {

    print $_ . "\n";

  }

}

 

Does anyone perhaps have some insight for me? 

 

Regards,

Chris.
