wofstream

I'm trying to find a good example of how to use these binary wide character versions of boost's serialization stuff. I pieced together some code to try and get it working, but unfortunately I get bombarded with linker errors when trying to compile it. Here's my code, in case I'm doing anything obviously wrong: #include <cstdlib> #include <iostream> #include <fstream> #include <string> #include <vector> #include <boost/archive/binary_woarchive.hpp> #include <boost/archive/binary_wiarchive.hpp> class testClass { public: testClass() { } testClass(const int intInput, const std::wstring stringInput

I want to output a text to a file via two pointers that I have declared: wchar_t *Col1="dsffsd", *Col2="sdfsf"; Here is what I have tried: std::ofstream fout; fout.open(NativeDatabasePathHist); fout<<"testing"; fout<<" "<<Col1<<" "<<Col2; fout.close(); And here is what I am getting: testing 113 113 Why is it that when I print Col1 and Col2 , I am getting numbers instead of strings? Dmitriy First, use std::wofstream instead of std::ofstream . Also, use the L prefix on your text string to indicate that your text is wide character text: wchar_t *Col1=L"dsffsd" Since you have written it using wide

I'm using Qt/C++ on a Linux system. I need to convert a QLineEdit 's text to std::wstring and write it into a std::wofstream . It works correctly for ascii strings, but when I enter any other character (Arabic or Uzbek) there is nothing written in the file. (size of file is 0 bytes). this is my code: wofstream customersFile; customersFile.open("./customers.txt"); std::wstring ws = lne_address_customer->text().toStdWString(); customersFile << ws << ws.length() << std::endl; Output for John Smith entered in the line edit is John Smith10 . but for unicode strings, nothing. First I thought that is

I wrote the following program using VS2008: #include <fstream> int main() { std::wofstream fout("myfile"); fout << L"Հայաստան Россия Österreich Ελλάδα भारत" << std::endl; } When I tried to compile it the IDE asked me whether I wanted to save my source file in unicode, I said "yes, please". Then I run the program, and myfile appeared in my project's folder. I opened it with notepad, the file was empty. I recalled that notepad supported only ASCII data. I opened it with WordPad, it was still empty. Finally the little genius inside me urged me to look at the file size and not surprisingly it was

I am currently writing an application which requires me to call GetWindowText on arbitrary windows and store that data to a file for later processing. Long story short, I noticed that my tool was failing on Battlefield 3, and I narrowed the problem down to the following character in its window title: http://www.fileformat.info/info/unicode/char/2122/index.htm So I created a little test app which just does the following: std::wcout << L"\u2122"; Low and behold that breaks output to the console window for the remainder of the program. Why is the MSVC STL choking on this character (and I assume

Honestly, I just don't get the following design decision in C++ Standard library. When writing wide characters to a file, the wofstream converts wchar_t into char characters: #include <fstream> #include <string> int main() { using namespace std; wstring someString = L"Hello StackOverflow!"; wofstream file(L"Test.txt"); file << someString; // the output file will consist of ASCII characters! } I am aware that this has to do with the standard codecvt . There is codecvt for utf8 in Boost . Also, there is a codecvt for utf16 by Martin York here on SO . The question is why the standard codecvt
