Hi Sven

Is Zinc being overly fussy with encoding or is ASCII only URL strings a standard.
the following fails in a workspace/playground.

'http://www.yr.no/place/Mexico/Nuevo_León/Monterrey/forecast.xml' asZnUrl

The url comes from the yr.no database (via api). It is vaild if you paste into a browser.
Let me know what you think

Thanks

Thanks Sven

I will have to first deconstruct the url and then reconstruct it as you mentioned.
We discussed this in the discord channel and came to the same conclusion.

I really like your final solution and will probably go with that.

Thanks

When ZnUrl parses a string representation of a URL it is indeed strict. As per the spec this must be ASCII.

Browsers typically allow a wider range of input.

But of course, these URLs are supported, you just have to construct them differently. If you use the direct construction API, you can use full Unicode.

ZnUrl new 

  scheme: #http; 

  host: 'www.yr.no'; 

  addPathSegments: #('place' 'Mexico' 'Nuevo_León' 'Monterrey' 'forecast.xml');

  yourself.

You'll see that the external representation of your URL is actually the following, which is acceptable to the parser.

'http://www.yr.no/place/Mexico/Nuevo_Le%C3%B3n/Monterrey/forecast.xml' asUrl.

BTW, I would do your request as follows (using XML Support) :

ZnClient new
  systemPolicy;
  http;
  host: 'www.yr.no'; 
  addPath: #('place' 'Mexico' 'Nuevo_León' 'Monterrey' 'forecast.xml');
  accept: 'text/xml' asMIMEType;
  contentReader: [ :entity | XMLDOMParser parse: entity contents ];
  get.

In my Pharo 7 image, this gives me a nice coloured, fully parsed DOM:

HTH,
