This category is sorted strangely, http://sv.wikipedia.org/wiki/Kategori:Svenska_kokboksf%C3%B6rfattare
A, B, E, G, H, L, B, M, N, F, J, R, Þ, S, W, Z, Å
Not only does B appear twice, and F after N, but the article sorted under "Þ" has {{STANDARDSORTERING:Tunberger, Pernilla}} where "STANDARDSORTERING" is Swedish for DEFAULTSORT, and there is no "Þ" (Icelandic Thorn) in sight.
