Non-ascii host/domain names are not handled properly

[sjm42]

For example, an URL like http://äläomista.fi/ is legal and works with a browser.

There is a catch: the web client should translate the dns names with non-ascii (UTF-8) chars properly,
and this example domain would translate into xn--lomista-4wab.fi

Okay, I was able to get away with this kind of code:

if let Ok(url) = Url::parse(url_s) {
    // Now we should have a canonical url, IDN handled etc.
    let url_c = String::from(url);
    // ... continue processing
}

Referring to: https://docs.rs/url/latest/url/struct.Url.html

Well, this is something that webpage could handle under the hood, I guess.
I would not mind if it did...

Hi @sjm42, thanks for flagging, and glad to hear you were able to work this out.
I'm keeping this issue open since I think it should be part of the library, but I won't be able to work on it anytime soon
