1 If one puts localized chars in wikilinks ikiwiki will escape it.
2 This works right from a technical point of view, but the URLs will become ugly.
4 So I made a patch which unaccent chars: <http://users.itk.ppke.hu/~cstamas/code/ikiwiki/unaccentpagetitlenames/>
5 This is a one liner change, but requires a bit of reordering in the code.
