StreamLayer 设置中文条件过滤时无返回结果？

{"name":鲁"L11712","source":"3","lat":31.748453,"lon":121.462614,"direction":0.0,
"gpsTime":1464856424000,"distance":16392.3,"speed":0.0,"status":"停车",
"placeName":"","tempw":0.0,"oilUse":0.0,
"shape":{"x":121.462614,"y":31.748453,"spatialReference":{"wkid":4326}},"hasGPS":true}

GeoEvent返回的数据格式如上，最后设置filter为{where:"status='停车'"},结果没有数据，用source='3'这样的就可以筛选出来？然后过滤名字也包含中文就没有结果，是不是不支持中文过滤啊？
即使加上URL编码也不行。
