Rated 4 out of 5 stars

I'm not a Czech, so consider my opinion an outside view. I find it really lame to have two dictionaries, one with diacritics and one without. There is only one way of correctly writing Czech. Why would anybody who writes without diacritics (i.e. incorrectly) bother using a spell checker in the first place?
