在群里面听到有人说起有一款新的编辑器 Sublime Text 2 很不错, 于是我下载下来试用了一下, 发现不支持
中文, 听说要安装什么插件, 不管了, 没打算用, 但... 我打开了我的一个源代码C文件, 突然发现了一点小错误, 就用
ST2修改后Ctrl+S保存了, 当时没在意什么, 到了几天后的今天, 一看, 突然代码中的中文全部变成了乱码, 用强大的Notepad++
也没能识别出文件的编码, 结果, 只好用 WinHex 查看 16进制 内容, 咋一看, 着实吓了我一跳, 中文居然被编码成1个汉字
4个字节, 而且还很有规律, ...
规律是每个汉字被加上了两个字节的C2/C3, 不懂是为什么!
比如原来一个中文的两个字节:11 22
结果可能就成为:C2 11 C2 22
擦, 无语, 吓得我汗下, 那么多的代码, 中文全没了....
所有的规律(数据为16进制):
C3 X1 C3 X2 => X1+40,X2+40
C3 X1 C2 X2 => X1+40,X2
C2 X1 C3 X2 => X1,X2+40
C2 X1 C2 X2 => X1,X2
乱码后:
