Hi,

I created a client with a Client-ID containing “ö”. When I try to delete the key, I get the following error:

```auto
{
    "code": "invalid-operation",
    "description": "The corresponding API users could not be found."
}

```

I’m able to rename the key, but deletion is not possible. I think it’s a fairly low-priority bug, but I wanted to let you know 🙂

`HTTP DELETE /api/v1/clientapplications/my_key_with_%C3%B6`

Hi @Ole and thanks for reporting this! A fix is on the way 🙂
