在批处理脚本中处理特殊字符
Processing Special Characters in Batch Scripting
我正在制作文件和文件夹加密批处理脚本，我使用 Fatih Kodak 的 program.
从批处理转换为 exe
我的脚本的某些部分将文件或文件夹的路径加密为字母数字字符。我从其他人那里得到了这个脚本，我稍微修改了一下以处理其他特殊字符，但它仍然无法处理所有特殊字符。喜欢 &.
这是代码

首先，Batch 不如其他语言的编译器聪明。像"&"这样的字符，是在一个命令后面加一个命令。例如，set "word=hello" & echo %hello%。所以，就像你所做的那样，(set "CHAR[tu]=&")，批量认为你正在这样做，(set "CHAR[tu]= & ")。
为避免给脚本造成混乱和 "headache"，只需使用 "^" 字符来指示您正在分配一个字符，例如 &、>、%，甚至是普通字符 a ,b,c 作为一个字符串。它不会对脚本产生太大影响，它只是执行它编写的代码。
这将起作用：(set "CHAR[tu]=^&").
附加信息：
如果你Setlocal EnableDelayedExpansion，你不能回显“！”字符， echo Hello! 甚至 echo Hello^!，你应该试试这个 echo Hello^^!.
