G'day...
I've got a function which checks that only allowed characters are
contained within a tainted piece of data, part of it looks like this:
if ($tainted =~ /^([$allowed_chars]*)$/) {
return $1;
}
Where $allowed_chars are the allowed characters. Question: What happens
if $allowed_chars contains characters that normally need to be escaped
within regular expressions? (E.g "\".)
How are they interpreted? (Would the "\" just escape the next character
appearing or would it be interpreted literally? I'm guessing the former,
as I'm pretty sure I can use "\d" to indicate a digit.)
Thanks!
