Entering &nbsp; in html view and switching back to 'normal' kupu view  
i found no &nbsp; any more; I looked into the dom using Firebug - no  
&nbsp;
The only suspicious line i found in kupu code is:
kupuploneeditor.js #103
'''
     if (/^<body[^>]*>(<\/?(p|br)[^>]*>|\&nbsp;)*<\/body>$/.test 
(contents)) {
         contents = ''; /* Ignore nearly empty contents */
     }
'''

If you want to have a serious i18n aware catalog you will have to use  
TextIndexNG - and TextIndexNG knows how to deal with html entities  
(hopefully); I would like to know if it is hard to locate the code  
where the entities are dropped - is it zope, plone or kupu? As long  
as it is not Python we definitively can handle :-P  People are unable  
to edit the image modules i put in otherwise.

If you can make &nbsp; persistent I owe YOU one ;-)

Let's find that.
Gogo.
