Hi Jari,
thanks for the bump.
ok, so it's fixed in 10.13. Assuming the following;
1. the "Store Data As " setting is set correctly. (WebServer Procedure, advanced tab).
In the example you posted this was set to utf-8, but the TPS file contained "Scandinavian".
Until we get Unicode support in Clarion 11, I recommend that you "store as" your local code page, which in your case is Scandinavian - so correct that in your app.
2. The incoming JSON is _always_ UTF-8 (which is what it should be.)
Therefore if you are using a Clarion Client program, the JSON output from there MUST be converted to unicode (utf-8) before it is sent.
Cheers
Bruce
