## Language Detection and Selection

### User Interface Language

Fess determines the UI language in this order:

        assertEquals(original, decoded.value, "Decoded value should match encoded value");
    }

    // If we have a routes left, use 'em.
    if (routeSelection?.hasNext() == true) return true

    // If we haven't initialized the route selector yet, assume it'll have at least one route.
    val localRouteSelector = routeSelector ?: return true

    // If we do have a route selector, use its routes.
    return localRouteSelector.hasNext()
  }
