无法使用Google API对日语地址进行地理编码

Question

我正在实施http://jsfiddle.net/Zf6LG/反向地理编码。

     $(function () {
     var lat = 44.88623409320778,
         lng = -87.86480712897173,
         latlng = new google.maps.LatLng(lat, lng),
         image = 'http://www.google.com/intl/en_us/mapfiles/ms/micons/blue-dot.png';

     //zoomControl: true,
     //zoomControlOptions: google.maps.ZoomControlStyle.LARGE,

     var mapOptions = {
         center: new google.maps.LatLng(lat, lng),
         zoom: 13,
         mapTypeId: google.maps.MapTypeId.ROADMAP,
         panControl: true,
         panControlOptions: {
             position: google.maps.ControlPosition.TOP_RIGHT
         },
         zoomControl: true,
         zoomControlOptions: {
             style: google.maps.ZoomControlStyle.LARGE,
             position: google.maps.ControlPosition.TOP_left
         }
     },
     map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions),
         marker = new google.maps.Marker({
             position: latlng,
             map: map,
             icon: image
         });

     var input = document.getElementById('searchTextField');
     var autocomplete = new google.maps.places.Autocomplete(input, {
         types: ["geocode"]
     });

     autocomplete.bindTo('bounds', map);
     var infowindow = new google.maps.InfoWindow();

     google.maps.event.addListener(autocomplete, 'place_changed', function (event) {
         infowindow.close();
         var place = autocomplete.getPlace();
         if (place.geometry.viewport) {
             map.fitBounds(place.geometry.viewport);
         } else {
             map.setCenter(place.geometry.location);
             map.setZoom(17);
         }

         moveMarker(place.name, place.geometry.location);
         $('.MapLat').val(place.geometry.location.lat());
         $('.MapLon').val(place.geometry.location.lng());
     });
     google.maps.event.addListener(map, 'click', function (event) {
         $('.MapLat').val(event.latLng.lat());
         $('.MapLon').val(event.latLng.lng());
         infowindow.close();
                 var geocoder = new google.maps.Geocoder();
                 geocoder.geocode({
                     "latLng":event.latLng
                 }, function (results, status) {
                     console.log(results, status);
                     if (status == google.maps.GeocoderStatus.OK) {
                         console.log(results);
                         var lat = results[0].geometry.location.lat(),
                             lng = results[0].geometry.location.lng(),
                             placeName = results[0].address_components[0].long_name,
                             latlng = new google.maps.LatLng(lat, lng);

                         moveMarker(placeName, latlng);
                         $("#searchTextField").val(results[0].formatted_address);
                     }
                 });
     });

     function moveMarker(placeName, latlng) {
         marker.setIcon(image);
         marker.setPosition(latlng);
         infowindow.setContent(placeName);
         //infowindow.open(map, marker);
     }
 });

但是在地址栏中输入这个日语地址“东京都新宿区市谷砂土原町319”（日本东京都新宿区Ichigayasadoharacho）和按Tab（onchange）不改变地图。 / p>

我无法弄清楚为什么这不起作用。在maps.google.com中搜索此地址=“东京都新宿区市谷砂土原町319”可以完美地显示地图。

任何帮助都将不胜感激。
