wofstream

I have to first read a file in Cyrillic, then randomly pick random number of lines and write modified text to a different file. No problem with Latin letter, but I run into a problem with Cyrillic text, because I get some rubbish. So this is how I tried to do the thing. Say, file input.txt is ааааааа ббббббб ввввввв I have to read it, and put every line into a vector: vector<wstring> inputVector; wstring inputString, result; wifstream inputStream; inputStream.open("input.txt"); while(!inputStream.eof()) { getline(inputStream, inputString); inputVector.push_back(inputString); } inputStream

I want to read hebrew(unicode) using xerces parser. I am able to read the value in XMLCh. However, while writing it to another file I get gargabe value. I tried using ofstream, wofstream but didnot helped. Let me know your suggestions The problem with wofstream is that it accepts the wide string for the open() method but does not actually write wide characters to the file. You have to be explicit about that and imbue() it with a locale that has a codecvt with the encoding you want. Implementation of such a codecvt that produces a UTF encoding is still spotty, here's an example that uses Boost.

I have a std::wstring whose size is 139,580,199 characters. For debugging I printed it into file with this code: std::wofstream f(L"C:\\some file.txt"); f << buffer; f.close(); After that noticed that the end of string is missing. The created file size is 109,592,584 bytes (and the "size on disk" is 109,596,672 bytes). Also checked if buffer contains null chars, did this: size_t pos = buffer.find(L'\0'); Expecting result to be std::wstring::npos but it is 18446744073709551615 , but my string doesn't have null char at the end so probably it's ok. Can somebody explain, why I have not all string

I am using Visual Studio C++ 2008 (Express). When I run the below code, the wostream (both std::wcout , and std::wfstream ) stops outputting at the first non-ASCII character (in this case Chinese) encountered. Plain ASCII characters print fine. However, in the debugger, I can see that the wstring s are in fact properly populated with Chinese characters, and the output << ... is in fact getting executed. The project settings in the Visual Studio solution are set to "Use Unicode Character Set". Why is std::wostream failing to output Unicode characters outside of the ASCII range? void PrintTable

#include <iostream> #include <fstream> #include <string> using namespace std; int main() { locale system(""); locale::global(system); wcin.imbue(system); wstring data; getline(wcin,data); wcout.imbue(system); wcout << data << L" length=" << data.length() << endl; locale utfFile("en_US.UTF-8"); wofstream file("my_utf_file.txt"); file.imbue(utfFile); file << data; file << endl; file.close(); return 0; } It's your system. Locale names are not part of the C++ standard, so "en_US.UTF-8" is not universally valid. It's not even certain that a locale similar to it exists. Won't work in an embedded
