The \Q and \E is the correct answer; the quotemeta() function is the equivalent function.

However, for perl5 anyway, a useful rule of thumb is that alphanumeric characters need escapes to be special, and everything else need escapes to be normal. There are a lot of non-alphanumeric characters that the escaping would be redundant but not harmful (such as \=).
