keep special characters in URL

When creating a page, the default URL segment validation automatically replaces special characters with their standard equivalents (e.g., "ä" is replaced with "a"). However, some clients may require these special characters to remain intact in URLs for non-English versions of their website.

var validChars = "ü ö ä ß ó ñ á á é í ó ő ú ü ñ";

For CMS 12

//Startup.cs
services.Configure<UrlSegmentOptions>(config => {
    config.SupportIriCharacters = true;
    config.ValidCharacters = @"A-Za-z0-9\-_~\.\$" + validChars;
});

For CMS 11

[InitializableModule]
[ModuleDependency(typeof(EPiServer.Web.InitializationModule))]
public class UrlSegmentConfigurationModule : IConfigurableModule
{
    public void ConfigureContainer(ServiceConfigurationContext context)
    {
        var validChars = "ü ö ä ß ó ñ á á é í ó ő ú ü ñ"; 
        context.Services.RemoveAll<UrlSegmentOptions>();
        context.Services.AddSingleton<UrlSegmentOptions>(s => new UrlSegmentOptions
        {
            SupportIriCharacters = true,
            ValidCharacters = @"\p{L}0-9\-_~\.\$" + validChars
        });
    }

    public void Initialize(InitializationEngine context){}

    public void Uninitialize(InitializationEngine context) { }
}
