加急:linux下wchar_t怎么输出?
wchar_t *w1 = L"中国";
cout << w1<< endl;
2.读取一个文件,比如编码是gb2312,需要怎么进行编码转换才能正确输出?
3.怎么将已知编码如gb2312的文件,转换另存为Unicode的文件?

浅谈c++ 字符类型总结区别wchar_t,char,WCHAR
1、区别wchar_t,char,WCHAR ANSI:即 char,可用字符串处理函数:strcat( ),strcpy( ), strlen( )等以str打头的函数。 UNICODE:wchar_t是Unicode字符的数据类型,它实际定义在里: typedef unsigned short wchar_t; 另外,在头文件中有这样的定义:typedef wchar_t WCHAR; 所以WCHAR实际就是wchar_t wchar_t 可用字符串处理函数:wcscat(),wcscpy(),wcslen()等以wcs打头的函数。为了让编译器识别Unicode字符串,必须以在前面加一个“
wchar_t,char,string,wstring之间的相互转换
在处理中文时有时需要进行wchar_t,char,string,wstring之间的转换。 其中char和string之间、wchar_t和wstring之间的转换较为简单,代码在vs2010下测试通过。 代码如下:#include <iostream>#include <string>#include <tchar>#include <Windows> using namespace std; //Converting a WChar string to a Ansi stringchar *w2c(char *pcstr,const wchar_t *pwstr, size_t l

Supports all standard char types: char, wchart, char16t, char32t and C++20's char8t. Motivation Standard C++ string classes - , etc. - aren't very efficient when it comes to memory usage and allocations. Due to small string optimization a lot of space can be wasted when storing huge amounts of long strings, that don't fit the capacity of the small string buffer. A common allocation strategy that uses (doubling the capacity when extending the storage) can lead to almost 50% waste of memory unless is called. StringPool was created to provide a way of storing strings that don't change thro...
