/^[\w\s.]+$/ is equivilant to /^.+$/, right? I suspect the trailing period in the class is not what you intended.

No Idea about the unicode fun with $string1, though.

    No, it's only any_letter and spaces (I hope). It's supposed to check that a filename only consists of letters (as opposed to control characters, which I'm filtering for).

    The trailing period is supposed to be there for the dot in the filename.

    Unicode makes things *hard*. :)

      But the period matches any character if it isn't escaped.
      /[\w\s\.]+/ # one or more word, space or period characters /[\w\s.]+/ # one or more word. space or *any* characters /.+/ # same as above

        Note that inside a character class, a period is not special: it means just period. So this:

        /[\w\s.]+/
        would match one or more of (word chars, space chars, periods) in any combination.

        In other words, your first two examples are equivalent, not your second two.
