ÅÄÖ: what is considered more SEO friendly URL

Question

As far as I can tell I shouldn\'t be using ÅÄÖ (somthing like they have no visual representation in ASCII??).

So what is considered more SEO friendly? Replacing i.e. all

Answer 1

For what it's worth, Wikipedia, one of the biggest and most prominent sites on the Internet, preserves all sorts of weird diacritics in its URLs. Conventions for changing diacritics to plain letters will vary between languages: Acute and grave accents in French can be safely removed. (The French themselves tend to remove them when writing in block capitals.) Fadas in Irish should be retained if possible, or cleanly removed. Diaereses may be simply stripped, or replaced with a double vowel, or replaced with vowel+e, depending on the language. And for languages written in the Greek or Cyrillic alphabets, there's no obvious system unless you want to go for full transcription.
