Get actions and default behavior for street name language

In Brussels, Dutch street names have priority over French street names, and roads do not have English names (en-US is the default value for lang). If you specify a request for turn-by-turn actions in Brussels, Dutch is the default language for the street names:

curl -X GET \
'https://router.hereapi.com/v8/routes?transportMode=car&origin=50.842556,4.375045&destination=50.842939,4.376699&return=polyline,actions,instructions,summary,turnbyturnactions&apikey={YOUR_API_KEY}'

{
  "nextRoad": {
    "name": [
      {
        "value": "Toulousestraat",
        "language": "nl"
      },
      {
        "value": "Rue de Toulouse",
        "language": "fr"
      }
    ]
  }
}
