Hi sven,
We are using Zinc (Gemstone) to access a restful interface.
I didnt find a solution to send an url with german characters like "Ã¶Ã¤Ã¼".
Am i missing something?
All such tests fails:
ZnUrl fromString: '%F6lo'.
ZnUrl fromString: 'Ã¶lo'.
ZnUrl fromString: 'Ã¶lo' encodeAsUTF8 asString.
json := (client := ZnClient new)
      url: url;
      accept: ZnMimeType applicationJson;
      contentReader: [ :entity | | parserClass |
      	parserClass := Smalltalk at: #JSJsonParser.
      	parserClass parse: entity contents ];
      ifFail: [:ex | ^ self error: 'HTTP request failed!' ];
      get.

This goes like this (in Pharo 4):
'Ã¤' utf8Encoded hex => 'c3a4'
'http://de.wikipedia.de/wiki/Enzyklop%C3%A4die' asZnUrl.
ZnUrl new
 scheme: #http;
 host: 'de.wikipedia.de';
 addPathSegment: #wiki;
 addPathSegment: 'EnzyklopÃ¤die';
 yourself.
Check the class comment: the print & parse forms are encoded, while the components & accessors are not.
Does this work for you ?

Gerhard solved his use case as follows:

ZnUrl new
  scheme: #http;
  host: 'dev.virtualearth.net';
  addPathSegments: #('REST' 'v1' 'Locations');
  queryAt: 'query' add: 'JÃ¤gerstraÃe';
  yourself.
