简繁体如何互相转化(100分)

简繁体如何互相转化[!]

又是内码转换，搜索一下本站的已答问题吧！

我也有此問題，我日常是用繁體工作，可有些諸如郵件和下載這類的東西大多是簡體，
動不動就看不清，十分惱火，如有良策請告知，為謝。

简繁体就是2套不同的编码
简繁体互相转化其实其实就是一个“字符映射”的问题
如 “法”字 在BG2132 中的内码是$B7 $AB
; ; ; ; ; ; 在BIG5 中的内码是$AB $6B
我们可以通过一张事先存好的映射表做内码转换

而转换质量的高低就取觉于映射表的好坏了

映射表 你自己可以到网上去找，我这没有现成的

EBOOK（开放源码的）中间也实现了内码转换（不过不是用映射表而是用映射函数）
你自己去找来看看吧，我刚换了一个地方很多东东都搞丢了：（

怎么就不会去搜索呢？
