So many weird letters that's were barely used. á, é, í, ó, ú are more optional word emphasisers that barely anyone uses. And ë is the most common glottal stop denoter, ï less common. I can't think of examples with ä, ö and ü though, and they're more common in German as umlauts loanwords if any.
English also has all those letters, in loanwords, yet the map doesn't say so. The language does take over unusual letters in loanwords. For instance: I have seen English texts write oeuvre as œuvre like in French. It's also written like that in dictionaries.
