In code-view, Zero-width space's are rendered, instead of being shown as code

[sirtet]

To reproduce:

Copy the sample text from ​http://en.wikipedia.org/wiki/Zero-width_space

to the demo ​http://ckeditor.com/demo#standard

and switch to Source. Here, the zerowidth's should be shown as ​, but they are rendered as zero-width.

Pasting

aaaaaa​​bbbbbbbbbbbbbb​​ccccccccccccccccccccc​​ddddddddddddddddd​​eeeeeeeeeeeeeeeeeeeeeeeeee​​fffffffffffffffffff​​ggggggggggggggggggggg

into the code-view, switching to WYSIWYG and back, the entities are also no longer viewed, but rendered.

I see that rendering Zero-width space's is the normal behaviour of textarea's, but for "The best web text editor for everyone"'s Source button, i expect the same result as when looking at the page's source.

Source-editors like ACE ​http://ace.c9.io/build/kitchen-sink.html

and CodeMirror ​http://w8tcha.github.io/CKEditor-CodeMirror-Plugin/

show at least that there is something, but that's also not the full solution, if you want to see in source, what EXACTLY is going on in your Text.

You need to use ​http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-entities_processNumerical.

Please see v=​http://dev.ckeditor.com/ticket/11099#comment:2 - this comment applies to this issue as well.

Thanks.

I could apply

 config.entities_processNumerical = true;

in a jsfiddle, but not on my drupal7 site, filed an issue here: ​https://drupal.org/node/2138877

Upon searching for the reason, i had problems with testing in-browser: ​http://ckeditor.com/forums/Support/Modify-CKEDITOR.config-in-browser-and-allpy-the-changes

1. I think you need to use:

   config.entities = true;
   config.entities_processNumerical = true;
   

2. Please also note that if you modify Full profile that uses full HTML then you need to use Full HTML in content area (for filtered HTML Drupal will apply its filters).

NOTE: space entity gets doubled. I have reported it here: #11185
