【问题标题】：special characters UTF-8 with folders带有文件夹的特殊字符 UTF-8

【问题描述】：

我有这个来自 jQuery File Tree PHP Connector 的 php 代码

这个 jQuery 文件树更新了 dir 中的所有文件，并且可以看到里面的所有东西

jQueryFileTree链接Here

此代码中的好消息是使用具有 UTF-8 特殊字符的文件但坏消息是它不适用于具有特殊字符的文件夹

当我点击文件中的普通文件夹时有特殊字符 = 工作，我可以看到所有文件

当我点击文件夹时，文件中有特殊字符 = 不工作，我看不到任何文件

标签： php jquery file utf-8 tree

【解决方案1】：

我发现的解决方法是使用 base64 对完整路径进行编码

所以 rel= 应该包含 base64_encode($Dir.$File)

当然在服务器端，你必须做一个base64_decode

有了这个，任何字符编码都没有问题

第 72 行必须在 jqueryFileTree.js 文件中进行更改

showTree( $(this).parent(), escape($(this).attr('rel').match( /.*\// )) );

变成

showTree( $(this).parent(), $(this).attr('rel') );
