C++ 各类编码转换源代码分享（自己写的）
本帖最后由 Crez.晔霖 于 2020-3-19 11:15 编辑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
wchar_t* AnsiToUnicode(std::string AnsiString)
{
char* AnsiByte = const_cast<char*>(AnsiString.c_str());
int Length = MultiByteToWideChar(CP_ACP, 0, AnsiByte, -1, 0, 0);
wchar_t* Result = new wchar_t;
MultiByteToWideChar(936, 0, AnsiByte, -1, Result, Length * 2);
Result += '\0';
return Result;
}
ANSI转Unicode
std::string UnicodeToAnsi(const wchar_t* UnicodeByte)
{
int Length = WideCharToMultiByte(CP_ACP, 0, UnicodeByte, -1, 0, 0, 0, 0);
char* ResultByte = new char;
WideCharToMultiByte(CP_ACP, 0, UnicodeByte, -1, ResultByte, Length, 0, 0);
ResultByte += '\0';
return ResultByte;
}
GB2312转Unicode
wchar_t* GB2312ToUnicode(std::string GB2312String)
{
char* GB2312Byte = const_cast<char*>(GB2312String.c_str());
int Length = MultiByteToWideChar(936, 0, GB2312Byte, -1, 0, 0);
wchar_t* ResultByte = new wchar_t;
MultiByteToWideChar(936, 0, GB2312Byte, -1, ResultByte, Length * 2);
return ResultByte;
}
Unicode转GB2312
std::string UnicodeToGB2312(wchar_t* UnicodeByte)
{
int Length = WideCharToMultiByte(936, 0, UnicodeByte, -1, 0, 0, 0, 0);
char* ResultByte = new char;
WideCharToMultiByte(936, 0, UnicodeByte, -1, ResultByte, Length, 0, 0);
ResultByte += '\0';
return ResultByte;
}
UTF8转Unicode
wchar_t* UTF8ToUnicode(std::string UTF8String)
{
char* UTF8Byte = const_cast<char*>(UTF8String.c_str());
int Length = MultiByteToWideChar(65001, 0, UTF8Byte, -1, 0, 0);
wchar_t* ResultByte = new wchar_t;
MultiByteToWideChar(65001, 0, UTF8Byte, -1, ResultByte, Length);
return ResultByte;
}
Unicode转UTF8
std::string UnicodeToUTF8(wchar_t* UnicodeByte)
{
int Length = WideCharToMultiByte(65001, 0, UnicodeByte, -1, 0, 0, 0, 0);
char* ResultByte = new char;
WideCharToMultiByte(65001, 0, UnicodeByte, -1, ResultByte, Length, 0, 0);
ResultByte += '\0';
return ResultByte;
}
备注：想要把转换成或直接在前面加(char*)或(unsigned char*)即可~
以后可能会补一些新的，谢谢支持~
