=head1 NAME

Pod::Weaver::Section::Encoding - add a encoding pod tag with encoding (for your Perl module)

=head1 VERSION

version 0.100830

=head1 OVERVIEW

This section plugin will produce a hunk of Pod giving the encoding of the document
as well as an encoding, like this:

    =encoding utf-8

It will look for the first package declaration, and for a comment in this form:

    # ENCODING: utf-8

You have to add C<[Encoding]> in your weaver.* configuration file:

    [@CorePrep]
    
    [Encoding]
    
    [Name]
    [Version]
    
    [Region  / prelude]
    
    ...

I stole this code from L<Pod::Weaver::Section::Name>.
