大家好,又见面了,我是全栈君 C++11增加了unicode字面量的支持,可以通过L来定义宽字符:str::wstring str = L”中国人”; 将宽字符转换为窄字符串需要用到codecvt...库中的std::wstring_convert 例: #include "stdio.h" #include #include #include<iostream...{ wstring wstr = L"中国人"; cout << "unicode编码:" << wstr.c_str() << endl; wstring_convert> converter(new codecvt("CHS")); string str
C++输出流对象cout能够保证的是将数据以二进制输出到输出设备,但输出设备(比如Linux shell或者Windows console)是否能够支持特定的编码类型的输出,则取决于输出环境。...比如Linux虚拟终端XShell,配置终端编码类型为GBK,则无法显示输出的UTF-8编码字符串。...上面通过Unicode字符的转换来完成字符串的转换,实际上C++提供了一个类模板codecvt用于完成Unicode字符串与多字节字符串之间的转换,主要分为4种: codecvt<char,char,mbstate_t...++11 codecvt //converts between UTF32 and UTF8 encodings,since C++11 上面的codecvt...每种codecvt负责不同类型编码的转换,但是目前编译器的支持情况并没有那么完整,一种locale并不一定支持所有的codecvt,程序员可以通过has_facet函数模板来查询指定locale下的支持情况

则采用: std::string wstring2utf8string(const std::wstring& str) { static std::wstring_convert<std::codecvt_utf8...} std::wstring utf8string2wstring(const std::string& str) { static std::wstring_convert< std::codecvt_utf8...wstring2string(const std::wstring& str, const std::string& locale)//locale = "chs"或"zh-cn" { typedef std::codecvt_byname...std::wstring string2wstring(const std::string& str, const std::string& locale) { typedef std::codecvt_byname
