RSS Feed validation: IRI found where URL expected - How to convert IRI link to the valid URL?

Question

I have created an RSS feed, that contains non-ASCII characters URLs (IRI). That's why it does not validate using Feed validator.

How important is that validation? As far as I know this is more or less a validation for legacy RSS readers?

Anyway, I would like to know how to convert IRI to URL in C#?
