It actually depends on where the "." is in the Regexp. In your case it is inside a Character Class "[]". So it is matching the "." character explicitly. Since \w is shorthand for the [a-zA-Z] character class. It is parsed as a character class instead of an escaped "w" character. So you could actually change the character class to be %r|[-\w_./]|. No need to further escape the "_", or "-" since it is at the beginning of the class (That's for another reason though).
