how to tell CKEditor not to convert French accents to HTML entities

Hi,

I would like to know how to tell CKEditor not to convert French accents to HTML entities.

I tried to put this in "Custom javascript configuration" into a profile but it's still changing accents to HTML:
CKEDITOR.config.entities = false;
CKEDITOR.config.entities_latin = false;

I cleared the cache of my browser and of Drupal.
I tried removing CKEDITOR and CKEDITOR.config to get just "entities = false;" or "config.entities = false;"
I am not sure of the syntaxe because I didn't find it anywhere.

I know this works with FCKeditor 6.x-2.0-rc2:
FCKConfig.ProcessHTMLEntities = false;
FCKConfig.IncludeLatinEntities = false;
