I noticed that merkle-damgard is spelled incorrectly. Correct spelling would be Damgård, but if
å cannot be used in a tag name for technical reasons, it can be substituted by
aa. I tried to use the edit link to rename it from
merkle-damgaard, but that apparently allows editing of all the text but not the name itself.
Alternative spellings of the Scandinavian Å have become a concern because of globalization, and particularly because of the popularization of the World Wide Web. This is to a large extent due to the fact that internet domains containing Scandinavian letters are not recognized by the DNS system, and do not feature on keyboards adapted for other languages. While it is recommended to keep the Å intact wherever possible, the next best thing is to use the older, double A spelling (e.g. "www.raade.com" instead of "www.råde.com"). This is because, as previously discussed, the Å/Aa indicates a separate sound. If the Å is represented as a common A without the ring (e.g. "www.rade.com") there is no indication that the A is supposed to represent another sound entirely. Even so, (mis-)representing the Å as just an A is particularly common in Sweden, as compared to Norway and Denmark.
