Sebastian Leupold wrote either remove the page names from the URL or do not use special characters in your page title - I do not see another option.

Is it possible in the - host settings: Friendly Url Settings - to make any rule that changes special caracters with any other not special caracters?
eg. if i would like to have the caracter "Æ" in the pagename to be changed with the caracters "ae"  - how would i write that rule?

Yes, I think this is big problem for sites with accentuated characters in page titles. Firefox convert them into its HTML interpretation, very bleh (eg. Služby becomes Slu%C5%BEby), Internet Explorer leaves accentuated character in URL (not nice also).

Of course we want human friendly URLs and MUST have accented characters in page titles (it looks ugly, page title without diacritcs). Universal help should be removing diacritics and leaving ASCII character intact (Služby -> Sluzby). It can be done easily via System.Globalization.CharUnicodeInfo class. I use it in my human-friendly SEO links, but I don't want hack DNN's friendly url mechanism :-)

I know this is an old thread, but I came across it while searching for something else.

I have developed a product which allows custom specification of Urls for DotNetNuke pages (tabs).  You can specify whatever Url you like for any tab in the Portal.  Typically, with pages like Služby  you would keep the name of the page, so that it appears correctly in the menus and links, but you would modify the url to Sluzby  so that when the Url is ascii-encoded for use in browser address bars, it doesn't have special characters converted into their encoded form.

You can read about the module at iFinity Url Master - Friendly Url Provider for DotNetNuke

The module is a complete replacement for the standard DNN Friendly Url provider, so you get all the same standard features plus a whole lot of other features, and it integrates cleanly without modification to the DNN Core.
