Encoding is hard. Recently had a problem where some proxy/load balancer (I think) in Go would crash, as it couldn't handle æøå in some headers which was returned from some service doing ip lookups before passing on the request. Which of course hit our workers in the city of Tønsberg.

Another example I remember from earlier days is the BOM in xml files. When it was wrong things could crash in all kind of weird ways, and impossible to see.
