I want to return in response the orginal text.

But when I have the letter ä, I'm sometimes getting �� instead.

e.g. for Stäblistraße, The cloud returns St��blistraße.
It's not always happened. But even one time is too much..

How can I verify it will never happened again?

I tried `utf8.decode(value)` But not working - `Error: Invalid continuation byte`.

Attached code snippet:

```
var sendResponse = function(res,response,type)
{
  res.writeHeader(200, {
    "Content-Type" : "text/plain"
  });
  res.write((JSON.stringify(response))+"\n");
  res.end();
}

```
