mui.openWindow url是中文目录是打开出错

如题，
error
请求的页面无法打开：file:///storage/emulated/0/Android/data/io.dcloud.HBuilder/.HBuilder/apps/HBuilder/www/lawPages%2F%E4%B8%AD%E5%9B%BD%2Fabout.html at file:///android_asset/data/error.html:41

代码：
mui.openWindow({
url: encodeURIComponent("lawPages/中国/about.html"),
id: "info",
show: {
aniShow: 'zoom-fade-out',
duration: 300
},
waiting:{
autoShow:false
},
extras:{
urlStr:"info..."
}//额外扩展参数
});
