I added a fixed encoding in my own code to test. Before I never saw the latin-1 appearing aynwhere. But I checked monticello and I did not alter zinc code. I'll check again. > On the other hand you are right: ZnUtils class>>writeQueryFields:on: does > indeed always use the UTF8 based #encodeForHTTP of which there is also an > encoding based variant that would be more correct I guess. > > I assume this is not a theoretical exercise and that you have actual code > failing because of this ? > Yes. I need to issue url safe encoded parameters. When it comes to character encoding of safe url encoded things it gets hairy pretty quick. While with GET requests this is heavy to solve at all a charset addition should help when doing posts. So at least for tesing I need to take control over the encoding. And I think there are a lot of latin-1 encoded url safe encoded URLs and strings out there. And the server I need to deal with does not accept the utf-8 encoded stuff. > Please file a bug report.

But the usage of the encoding is burried deep in the process so I couldn't came up with an easy fix looking the first time. > Thanks for reporting this. > > Sven > > PS: ZnNeoClient has been renamed ZnClient since more than a month, you > probably best use the latest version. > Yes, I know. As I wrote I tested this with #13315 and there is only ZnNeoClient. I updated pharo two times and rolled back. Then I remember you call it "the client has been renamed" but my code those not work with ZnClient. It looks as it has less in common with ZnNeoClient. So I postpone upgrading day after day :) Norbert
