Hi Volkert, Thanks for the test case, it helped me figure out what the problem was. Basically, what Norbert said was 100% correct: the server code (Teapot) should have specified the charset or encoding of the mime-type it was using (so application/json;charset=utf-8 instead of just application/json). However, I thought I had changed the default to be utf-8, so I was surprised it was not picked up. It turned out utf-8 was the default for reading/writing http messages and their entities, but not so when manually constructing instances (like Teapot did). In code, json := '{''bank'':''Région Genève Rhône''}'. entity := ZnEntity with: json type: 'application/json'. response := ZnResponse ok: entity. response encoder. did not return a ZnUTF8Encoder but a ZnNullEncoder. I changed that now. === Name: Zinc-HTTP-SvenVanCaekenberghe.428 Author: SvenVanCaekenberghe Time: 2 May 2015, 7:09:55.832482 pm UUID: 6376bd91-2a95-4265-bfff-e3c6626aee79 Ancestors: Zinc-HTTP-SvenVanCaekenberghe.427 Change ZnStringEntity>>#initializeEncoder to default to ZnUTF8Encoder unless ZnDefaultCharacterEncoder is set Change ZnEntityReader>>#readEntity to no longer use #withDefaultUtf8Decoder: (and remove it) Change ZnEntityWriter>>#writeEntity: to no longer use #withDefaultUtf8Encoder: (and remove it) Add ZnResponseTests>>#testDefaultUTF8Encoding === Name: Zinc-Tests-SvenVanCaekenberghe.226 Author: SvenVanCaekenberghe Time: 2 May 2015, 7:10:12.331593 pm UUID: 9010fbd6-bf9d-400e-b463-cb73920b79f6 Ancestors: Zinc-Tests-SvenVanCaekenberghe.225 Change ZnStringEntity>>#initializeEncoder to default to ZnUTF8Encoder unless ZnDefaultCharacterEncoder is set Change ZnEntityReader>>#readEntity to no longer use #withDefaultUtf8Decoder: (and remove it) Change ZnEntityWriter>>#writeEntity: to no longer use #withDefaultUtf8Encoder: (and remove it) Add ZnResponseTests>>#testDefaultUTF8Encoding === for now, in #bleedingEdge of Zinc HTTP Components.

I thought UTF-8 is the default encoding in case JSON Documents, and so for the Content-Type: application/json.
I added "setCharSetUTF8" this Teapot-Output and all works fine now. :-) Fine, but I still think this is strange, it should work by default too. But to understand what went wrong, I need an example (server+client) that I can run.
Danke, Volkert

You need to look at the headers of the request. I would assume the sender sets an Content-Type: application/json without charset. In that moment it is uncertain what has to be done because the server needs to assume what charset it might be and this tasks seldomly works out good. In order to make it work set a content type of your entity this way
ZnMimeType applicationJson setCharSetUTF8
Now you send a Content-Type of application/json;charset=utf-8 and the server knows which character decoder to use. That should be it. So please always assign a char set to your sending data to make it more reliable what happens on the other end.
hope this helps,
Norbert

The JSON is served with ZnServer / Teapot. ;-)

Hi Volkert,
Tip 1: use ZnClient and inspect the response in detail, more specifically to see whether the response content type specifies the encoding.
ZnClient new get: ' http:// <removed>/api/atm/801813'; yourself.
Tip 2: you could try to force override the default encoding using ZnDefaultCharacterEncoder (see the class comment).
But recent Zn code defaults to UTF8 (see #withDefaultUTF8Decoding: and #withDefaultUTF8Encoding:). So I am curious to see the response headers.
HTH,
Sven

Dear all,
i am trying to get a JSON Document with ZnEasy. The Document is UTF-8 encoded.
(ZnEasy get: ' http:// <removed>/api/atm/801813') entity string. <gccacjeh.png>
Any hints?
