First, your posted data isn't valid JSON. This would be:

{"value": "aériennes"}

Note the double quotes: They are required.

The Content-Type for JSON data should be application/json. The actual JSON data (what we have above) should be encoded using UTF-8, UTF-16, or UTF-32 - I'd recommend using UTF-8.

Once the JSON reaches the browser, it should good, if it is valid. However, how are you inserting the data from the JSON response into the webpage?
