    There is no foolproof way of differentiating between some of the encodings.
    While UTF-16 or UTF-8 with a BOM (such files don't necessarily start with a BOM
    by the way) "stand out" as being unlikely to be in any other encoding others
    are more troublesome.

    If there is no source of encoding information (such as you get with xml
    declarations, HTTP headers and such), and even if there is, it may be best to
    offer your users the ability to select encodings (perhaps with the default
    choice based on locale settings).
