tinyMCE config file location

I found only this:

if (settings.verify_html === false)
	settings.valid_elements = '*[*]';

But not sure if this is right.
Also that there was a tinymce bug in one or several version that didn’t recognize this *[*] – is that true?

esmi have you working with custom styles in tinymce editor? I’m looking for solution that will add <i> tag to each <li> element.

I try this:

function custom_mce_before_init_insert_formats($init_array) {
    $style_formats = array(
        array(
            'title' => 'arrow',
            'inline' => 'i',
            'classes' => 'icon',
            'wrapper' => false,
            'exact' => true
        )
    );
    $init_array['style_formats'] = json_encode($style_formats);

    return $init_array;
}
add_filter('tiny_mce_before_init', 'custom_mce_before_init_insert_formats');

but this add <i>as wrapper of content of <li> element so the result is:
<li><i class="icon">item 1</i></li>

but I want this:

<li><i class="icon"></i> item 1</li>

Thank you

OK,

hopefully I have found solution – I must create custom shortcode plugin. This plugin is generate <i> tag into <li> as I want. There is just need to replace some string and loop over every<li> tag.
Thanks anyway
