c++ unicode编码

stl

宏定义，使string和wstring通知支持

#ifdef _UNICODE #define tstring wstring #else #define tstring string #endif // _UNICODE #boost

boost

boost::log 只创建文件ascii文件，unicode需要转换后写入文件

wstring 转string boost::locale::conv::from_utf(wstr, “GBK”);

string转wstring boost::locale::conv::to_utf<wchar_t>(strGbk, “gbk”);

宽字符使用wchar_t，ascii使用char否则，调用一下函数还是乱码

代码语言：javascript复制

boost::locale::conv::between(str, "GBK", "UTF-8");   //utf8转gbk
boost::locale::conv::between(str, "UTF-8", "GBK");   //gbk转utf8
boost::locale::conv::to_utf<wchar_t>(str, "GBK");   //gbk转unicode
boost::locale::conv::from_utf(wstr, "GBK");         //unicode转gbk
boost::locale::conv::from_utf(wstr, "UTF-8");       //unicode转utf8
boost::locale::conv::utf_to_utf<wchar_t>(str);      //utf转utf

unicode

utf8和utf16是unicode的子集

unicode ascii 区块链
