I have a program that generates a text file interspersed with the unprintable characters turned into hex codes in the form [0xff]

I have been trying to write a one shot regexp that would trawl through the entire document and convert the hex codes back into the characters, but this code is the best I can come up with.

Can anyone see a better way to do it?

while ( my ( $hex ) = ($line =~ m/\[0x(..?)\]/)) {
    my $chr =  pack("h*", $hex);
    #print "$line \n Found hex value '$hex', equals char $chr\n";
    $line =~ s/\[0x$hex\]/$chr/;
}
