Javascript Phonegap/Cordova检查带有特殊字符的文件

Javascript Phonegap/Cordova检查带有特殊字符的文件,javascript,android,cordova,phonegap-build,Javascript,Android,Cordova,Phonegap Build,我想在应用程序第一次启动时下载所需的图像。我在下载之前检查文件是否存在,但在某些特殊字符方面有问题。空格似乎是自动编码的,但我如何检查一个名为file:///data/data/de.test.app/files/data/img/Pre+ƒ-test.jpg?我检查文件(在我确保deviceready事件触发后)时使用: 我试过了 path = "file:///data/data/de.test.app/files/data/img/Pre+ƒ-test.jpg"; path = "file

你的文件插件版本是什么?我在File plugin 1.3中遇到了类似的问题,并解决了这个问题:

        LocalFilesystemURL localURL = null;
        int shortestFullPath = 0;
