Problem with German umlauts with the API function Get

[Harald]

When I get a record via API the German umlauts are transmitted incorrectly. Jürgen becomes J\u00fcrgen.

How can I change this?

json_encode($data, JSON_UNESCAPED_UNICODE) json_decode($json, false, 512, JSON_UNESCAPED_UNICODE)

I think your suggestion is for PHP, do you also have a solution for Javascript?
