This is most likely based on outdated information.

It is surprising that these characters are not replaced. However all browsers and search engines can handle UTF-8 urls nowadays.

I would not change core files (like class.format.php), as I don't think this is a problem. Large sites are using UTF-8 URLs, e.g. https://vi.wikipedia.org
