NAME
    HTML::Mason::Escapes - Functions to escape text for Mason

DESCRIPTION
    This module contains functions for implementing Mason's substitution
    escaping feature. These functions may also be called directly.

    html_entities_escape
        This function takes a scalar reference and HTML-escapes it using the
        "HTML::Entities" module. By default, this module assumes that the
        string it is escaping is in ISO-8859-1 (pre Perl 5.8.0) or UTF-8
        (Perl 5.8.0 onwards). If this is not the case for your data, you
        will want to override this escape to do the right thing for your
        encoding. See the section on User-defined Escapes in the Developer's
        Manual for more details on how to do this.

    url_escape
        This takes a scalar reference and replaces any text it contains
        matching "[^a-zA-Z0-9_.-]" with the URL-escaped equivalent, a
        percent sign (%) followed by the hexadecimal number of that
        character.

    basic_html_escape
        This function takes a scalar reference and HTML-escapes it, escaping
        the following characters: '&', '>', '<', and '"'.

        It is provided for those who wish to use it to replace (or
        supplement) the existing 'h' escape flag, via the Interpreter's
        "set_escape()" method.

        This function is provided in order to allow people to return the
        HTML escaping behavior in 1.0x. However, this behavior presents a
        potential security risk of allowing cross-site scripting attacks.
        HTML escaping should always be done based on the character set a
        page is in. Merely escaping the four characters mentioned above is
        not sufficient. The quick summary of why is that for some character
        sets, characters other than '<' may be interpreted as a "less than"
        sign, meaning that just filtering '<' and '>' will not stop all
        cross-site scripting attacks. See
        http://www.megasecurity.org/Info/cross-site_scripting.txt for more
        details.
