/**
* It's surprisingly difficult to keep posts consistent through various processes.
* I'll keep some notes here for future me or future developers woring on this.
*
* The text that is passed off in "process" must have HTML entities made safe, any
* non char set characters converted into their numeric equivalent &#xxx; make
* every effort to not auto-parse typed in entities. That is, if someone types in &#39; it
* should NOT convert that to ' when they hit submit.
* Test input: < > ' " & ¦ $ \ ! &amp; &#39; &quot; &lt; &gt; &para;
* Should be processed as: &lt; &gt; &#39; &quot; &amp; ¦ $ &#92; ! &amp;amp; &amp;#39; &amp;quot; &amp;lt; &amp;gt; &amp;para;
* This is *the* golden rule. Use this to test any fixes. It must work in the following modes:
* RTE > STD Switch
* STD > RTE Switch
* RTE > Preview
* STD > Preview
* RTE > Edit
* STD > Edit
* RTE > Edit > More options
* STD > Edit > More options
* RTE > Quote from post
* STD > Quote from post
*
* Please test all these modes when you have finished modifying this class
