When writing web scripts...

Do you maintain super strict 80 columns only rule?

Do you let it slide a little?

Do you try to keep 80 columns but if a single line goes way over you leave it like that?

I've got a line in my script for cleaning user-input strings that goes like this:

$string =~ s/[\x{fdd0}-\x{fdef}\x{fffe}\x{ffff}\x{1fffe}\x{1ffff}\x{2fffe}\x{2ffff}\x{3fffe}\x{3ffff}\x{4fffe}\x{4ffff}\x{5fffe}\x{5ffff}\x{6fffe}\x{6ffff}\x{7fffe}\x{7ffff}\x{8fffe}\x{8ffff}\x{9fffe}\x{9ffff}\x{afffe}\x{affff}\x{bfffe}\x{bffff}\x{cfffe}\x{cffff}\x{dfffe}\x{dffff}\x{efffe}\x{effff}\x{ffffe}\x{fffff}]//g;

I don't think there's anything I can do about it.
