Remove/stop 'redactor-inline-converted' Not specifically a Craft problem but I'm struggling to find an answer from Redactors site.

I've got over 100 occurrences of class="redactor-inline-converted" littered throughout the markup of Rich Text fields. How can I stop Redactor adding this class?

Here's the steps to recreate this. It's an odd thing between Redactor and Word.


Have styled text in Word with a superscript
Copy / paste in to Craft
Add some text and format it
Check the source and Redactor will add class="redactor-inline-converted"


This happens randomly on all tags:

&lt;strong class="redactor-inline-converted"&gt;&lt;em class="redactor-inline-converted"&gt;Superscript&lt;/em&gt;&lt;/strong&gt;
&lt;ul&gt;&lt;li&gt;&lt;em class="redactor-inline-converted"&gt;list item&lt;/em&gt;&lt;/li&gt;&lt;/ul&gt;

Not a solution, but I strip it out as part of a cleanup macro that runs on body text.

{% macro cleanup(string) -%}
    {%- if string|length -%}
        {{- string|typogrify|replace('&lt;p&gt;&lt;br&gt;&lt;/p&gt;','')|replace('redactor-inline-converted','')|raw -}}
    {%- endif -%}
{%- endmacro %}
