For the latest documentation about current CKSource projects, including software like CKEditor 4/CKEditor 5, CKFinder 3, Cloud Services, Letters, Accessibility Checker, please visit the new documentation website.

If you look for an information about very old versions of CKEditor, FCKeditor and CKFinder check also the CKEditor forum, which was closed in 2015. If not, please head to StackOverflow for support.


This option tells the editor to HTML encode some characters before posting the editor data. The encoded chars are: &, < and >. For example, if it is set to false:

FCKConfig.HtmlEncodeOutput = false ;

the editor posts code like this:

<p>Some text.</p>

If set to true:

&lt;p&gt;Some text.&lt;/&gt;
