I found this on accident while discussing at https://de.wikipedia.org/wiki/Wikipedia:Fragen_zur_Wikipedia#Suche_nach_.C3.9F. * [`insource:/außer/`](https://de.wikipedia.org/w/index.php?title=Spezial:Suche&search=insource%3A%2Fau%C3%9Fer%2F&fulltext=1&profile=) returns nothing. * [`insource:/au[ß]er/`](https://de.wikipedia.org/w/index.php?title=Spezial:Suche&search=insource%3A%2Fau%5B%C3%9F%5Der%2F&fulltext=1&profile=) returns nothing. * [`insource:/au[ ß]er/`](https://de.wikipedia.org/w/index.php?title=Spezial:Suche&search=insource%3A%2Fau%5B+%C3%9F%5Der%2F&fulltext=1&profile=) returns the expected results for "außer". I have no idea why. What does the space do? I tried other combinations of characters, e.g. `[ a]`, but in most cases this does what I expect. There is something very, very special about the German "ß".
