javascript - Not able to geo code japanese address using google API -

i implementing http://jsfiddle.net/zf6lg/ reverse geocoding.

     $(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);      }  }); 

but in address field when enter japanese address "東京都新宿区市谷砂土原町３１９" (which "ichigayasadoharacho, shinjuku, tokyo, japan") , press tab (onchange) not change map.

i not able figure out why not work. searching address = "東京都新宿区市谷砂土原町３１９" in maps.google.com shows map perfectly.

any appreciated.
