Hi All,


I need a c++ program which will read a unicode format file and store in another file.Before reading the file the program should able to check whether the file is in unicode format or not.if not no need to read and store.

I never worked on unicode file ,so i do not know how to deal with it.

Please any one can help me!!!Its urgent.

Here is the code what i have tried but i dont know whether it exactly doing the job or not.As i am no clear idea about the multi-byte foramt file,so i am not getting the things exactly.

#include <iostream>
#include<fstream>
#include<string>
using namespace std;
int main()
{
	wchar_t ch;
	FILE *fp;

	wchar_t *buffer = (wchar_t *)malloc(sizeof(wchar_t) * 1);
 
	fp = fopen("in.txt","rb");
 
	if( fp == NULL)
	{
		printf("Error: File cannot be access/opened\n");
		getchar();
		return 1;
	}
	else
	{
		while(fread(buffer,sizeof(wchar_t),1,fp) != 0)
		   printf("%s",buffer);
		fclose(fp);
	}
 
   system("PAUSE");
	return 0;
}

Thanx in Advance

Regards
Samir

I can't help with your problem, but might I suggest not using C-specific functions in your C++ code? It's merely bad practice, and can be unsafe. Use std::cout for output and std::cin for input. Avoid using system calls where viable alternatives exist. system("pause") can be replaced with std::cin.get().

What operating system are you on? Unfortunately unicode has not turned out be as easy as I would have hoped (which is probably why it has not been as widely adopted as people would like).

It would be nice if you could just use wcout and wprintf -- but alas these seems to require some work to get working. First of all if you are on windows (I don't know about linux) the console does not support Unicode past the ASCII encoding -- i.e. it don't work with unicode. Even to get basic unicode support you have to change the font to Lucinda.

The following program does not work under windows, but if I am not mistaken (and I might be because I don't have a linux box set up at the moment) this *should* work under linux:

#define UNICODE
#include <iostream>
#include <string>
#include <wchar.h>


int main() {
	std::wstring tryme = L"This is a test";
	wchar_t greekStr[] = {0x03B1, 0x03B2, 0x03B3, 0x03B4, 0x03B5, 0x03B6, 0x0000 };
	
	std::wcout << tryme << std::endl;
	std::wcout << greekStr << std::endl;

}
