C++ 各类编码转换源代码分享（自己写的）

Crez.晔霖

来分享一下自己写的各类编码转换，大部分测试可用，部分没有测试，当然适量参考了一下网络资源哈

废话不多说，上代码：
Unicode转ANSI

1. wchar_t* AnsiToUnicode(std::string AnsiString)
   
2. {
   
3.         char* AnsiByte = const_cast<char*>(AnsiString.c_str());
   
4.         int Length = MultiByteToWideChar(CP_ACP, 0, AnsiByte, -1, 0, 0);
   
5.         wchar_t* Result = new wchar_t[Length * 2];
   
6.         MultiByteToWideChar(936, 0, AnsiByte, -1, Result, Length * 2);
   
7.         Result += '\0';
   
8.         return Result;
   
9. }

ANSI转Unicode

1. std::string UnicodeToAnsi(const wchar_t* UnicodeByte)
   
2. {
   
3.         int Length = WideCharToMultiByte(CP_ACP, 0, UnicodeByte, -1, 0, 0, 0, 0);
   
4.         char* ResultByte = new char[Length * 2];
   
5.         WideCharToMultiByte(CP_ACP, 0, UnicodeByte, -1, ResultByte, Length, 0, 0);
   
6.         ResultByte += '\0';
   
7.         return ResultByte;
   
8. }

GB2312转Unicode

1. wchar_t* GB2312ToUnicode(std::string GB2312String)
   
2. {
   
3.         char* GB2312Byte = const_cast<char*>(GB2312String.c_str());
   
4.         int Length = MultiByteToWideChar(936, 0, GB2312Byte, -1, 0, 0);
   
5.         wchar_t* ResultByte = new wchar_t[Length * 2];
   
6.         MultiByteToWideChar(936, 0, GB2312Byte, -1, ResultByte, Length * 2);
   
7.         return ResultByte;
   
8. }

Unicode转GB2312

1. std::string UnicodeToGB2312(wchar_t* UnicodeByte)
   
2. {
   
3.         int Length = WideCharToMultiByte(936, 0, UnicodeByte, -1, 0, 0, 0, 0);
   
4.         char* ResultByte = new char[Length * 2];
   
5.         WideCharToMultiByte(936, 0, UnicodeByte, -1, ResultByte, Length, 0, 0);
   
6.         ResultByte += '\0';
   
7.         return ResultByte;
   
8. }

UTF8转Unicode

1. wchar_t* UTF8ToUnicode(std::string UTF8String)
   
2. {
   
3.         char* UTF8Byte = const_cast<char*>(UTF8String.c_str());
   
4.         int Length = MultiByteToWideChar(65001, 0, UTF8Byte, -1, 0, 0);
   
5.         wchar_t* ResultByte = new wchar_t[Length * 2];
   
6.         MultiByteToWideChar(65001, 0, UTF8Byte, -1, ResultByte, Length);
   
7.         return ResultByte;
   
8. }
   

复制代码

Unicode转UTF8

1. std::string UnicodeToUTF8(wchar_t* UnicodeByte)
   
2. {
   
3.         int Length = WideCharToMultiByte(65001, 0, UnicodeByte, -1, 0, 0, 0, 0);
   
4.         char* ResultByte = new char[Length * 2];
   
5.         WideCharToMultiByte(65001, 0, UnicodeByte, -1, ResultByte, Length, 0, 0);
   
6.         ResultByte += '\0';
   
7.         return ResultByte;
   
8. }

备注：想要把[wchat_t*]转换成[char*]或[unsigned char*]直接在前面加(char*)或(unsigned char*)即可~
以后可能会补一些新的，谢谢支持~
