+			<p>Files should be saved with Unicode (UTF-8) encoding.  The <abbr title="Byte Order Mark">BOM</abbr>
+				should <em>not</em> be used.  Unlike UTF-16 and UTF-32, there's no byte order to indicate in
+				a UTF-8 encoded file, and the <abbr title="Byte Order Mark">BOM</abbr> can have a negative side effect in PHP of sending output,
+				preventing the application from being able to set its own headers.  Unix line endings should
+				be used (LF).</p>
+			
+			<p>Here is how to apply these settings in some of the more common text editors.  Instructions for your
+				text editor may vary; check your text editor's documentation.</p>
