You should set the character map on UrlSegmentOptions instead, see https://world.episerver.com/documentation/developer-guides/CMS/routing/internationalized-resource-identifiers-iris/

Hi Johan,

Thanks for your answer.

I've tried to make it working on the UrlSegmentOptions, but till so far it doesn't work.

Could you have a look at the code below and see anything I'm doing wrong?

[ModuleDependency(typeof(EPiServer.Web.InitializationModule))]
public class IRIConfigurationModule : IConfigurableModule
{
public void ConfigureContainer(ServiceConfigurationContext context)
{
var options = new UrlSegmentOptions();
options.CharacterMap.Add('Š', 'S');

context.Services.AddSingleton<UrlSegmentOptions>(options);
}

public void Initialize(InitializationEngine context)
{ }

public void Uninitialize(InitializationEngine context)
{ }
}

Thanks in advance!
