API : user.create does not like some characters (charset issue ?) => Invalid JSON

[gerard-wl]

If I send
{"jsonrpc": "2.0", "method": "user.create", "params": {"alias":"A1234", "name":"Duij", "surname":"Catherine", "usrgrps": [ { "usrgrpid": "91" }, { "usrgrpid": "92" }, { "usrgrpid": "3" }, { "usrgrpid": "5" }], "user_medias": [{ "mediatypeid": "1", "sendto":["[email protected]"]}]}, "id":1, "auth" : "ab966788bde641cfefb98d25b2c15522"}
its works
But if "name" is "Drießen" or "Malacé" (german or french characters) i get "Invalid Json"
What can I do ?

You need to make sure you are using utf-8.

Yes sorry, it works in binary utf-8
