CKEditor unwanted   characters

After some research I might shed some light on this issue - unfortunately there is no out-of-the-box solution.

In the CKEditor there are four ways a no-break space can occur (anybody know more?):

1. Automatic filling of empty blocks. This can be disabled in the config:

   config.fillEmptyBlocks = false;

2. Automatic insertion when pressing TAB-key. This can be disabled in the config:

   config.tabSpaces = 0;

3. Converting double spaces to SPACE+NBSP. This is a browser behavior and will thus not be fixed by the CKEditor team. It could be fixed serverside or by a clientside javascript onunload. Maybe this php is a start:

   preg_replace('/\s \s/ig', ' ', $text);

4. By copy & paste. If you paste a UTF-8 no-break space or double-spaces CKEditor will convert it automatically. The only solution I see here is doing a regex as above. config.forcePasteAsPlainText = true; doesn't help.

Summary: To get rid of all no-break spaces you need to write an additional function that cleans user input.

Comments and further suggestions are greatly appreciated! (I'm using ckeditor 3.6.4)

There is another way that a non breaking space character can occur. By simply entering a space at the end of a sentence.

CKEditor escapes basic HTML entities along with latin and greek entities.

Add these config options to prevent this (you can also add them in your config file):

CKEDITOR.on( 'instanceCreated', function( event ) { editor.on( 'configLoaded', function() {  editor.config.basicEntities = false;  editor.config.entities_greek = false;   editor.config.entities_latin = false;   editor.config.entities_additional = ''; });});

These options will prevent CKEditor from escaping nbsp gt lt amp ' " an other latin and greek characters.

Try:

config.basicEntities = false;

for me fixed the problem.
