Inconsistent administrative_area_level_1 geocode for same city (accented)

Question

My simple app has been working quite well until a client reported a bug as mentioned in the title. Google return sometime accent-removed result :

{
           "long_name" : "Hanoi",
           "short_name" : "Hanoi",
           "types" : [ "administrative_area_level_1", "political" ]
        }

And accented one:

 {
           "long_name" : "Hà Nội",
           "short_name" : "Hà Nội",
           "types" : [ "administrative_area_level_1", "political" ]
        }

I have tried applying API key (with language = french) but no luck.

As the result, my logic to group address by city , district failed!

BTW, do you guys have any good hints to automatically group address into district, city, country using data from google geocode or any other provider

Thank you

Answer 1

If you want French as a language of your resulting data you have to mention that in your language parameter of your request.

However, to group addresses into district city and country you can use the following API request.

https://maps.googleapis.com/maps/api/geocode/json?address=Winnetka&language=fr&key=API_KEY

In the response your district will be administrative_area_level_2 the states will be administrative_area_level_1 while the country will be the country parameter.

I am posting the JSON for the above request.
