But still the decoder in khtml is only made for rendering (i.e. readonly). So 
if we want to use this for editors, we need a "safe for saving" flag. If you 
open iso-8859-15 without non-ASCII letters as ASCII, there won't be any harm 
done. But as soon as you skip letters or merge letters or whatever we're 
talking data loss. So the decoder as is should not be used for files that 
will be saved later.
