使用此代码将Javascript ascii转换为unicode

我正在尝试将以本地ascii非英语字体编写的文本转换为标准unicode。问题是，我们必须使用映射文件将每个字符映射到哪个unicode字符。幸运的是，我在firefox插件中找到了一段现成的开源代码

它是更大的应用程序的一部分，我不知道如何独立使用它。此代码的功能实际上是将ascii字体中的文本转换为标准unicode

代码如下：

我想让这一切顺利。将文本转换为文本输入，并将结果输入其他输入

更新：抱歉没有正确解释。语言是印度语。之前的字符没有标准化，直到我猜我是正确的。所以人们习惯于按自己的意愿制作字体。其中的文本是现在。现在，在unicode出现之后，有许多标准字体可以在web上正确呈现，并被新网站和所有其他网站使用。已经有一些用python编写的脚本用于转换此文件。这是你的电话号码 我粘贴的javascript代码来自firefox中的一个插件，该插件将网页的字体转换为我想要转换的标准unicode字体。这个插件很大，适用于30多种语言。我只想要这个，所以拿了这个文件。但我能想出我该怎么做。希望这个解释是正确的。

这样行吗

var s = "..."; // your input string
var r = ""; // result
for (i in s) {
    r += Panchami.lookup(s[i]);
}
alert(r);

结束问题，因为问题涉及社区根本不知道的地方问题

ascii非英语-没有这样的野兽。它不是ASCII码就是非英语码。并确保您理解顶部的GPL文本的真正含义，特别是如果您正在开发商业、专有软件。@paxdiablo例如拼音，它是ascii和非英语的，不是吗？@pax哦，它可以是罗马日语，使用ascii字符，但不是英语；没错，@esafwan，你到底想做什么？Javascript中的所有字符串都是Unicode，Unicode与ASCII向后兼容，那么为什么需要转换呢？ASCII也不能包含非拉丁字符。所以你的问题没有多大意义。你能详细说明一下吗？我想那不是ascii码。。这是一种非unicode字体，我想转换，我的应用程序也是GPL。我想你也混淆了字体和字符集。字体类似于Helvetica或Arial，与Unicode或非Unicode无关。那么，假设您谈论的是一个编码在非Unicode字符集中的字符串，那么这个字符串从何而来？我想你是在服务器上输出它，然后在浏览器中查看它会变成胡言乱语？那么Javascript不是解决这个问题的方法。请详细解释你的实际问题。
