I wanted to know why 'wchar_t' data type is required if a 'char' can very
well hold all the characters on a given OS. To elaborate, I run the program
below on a Japanese Win 2K Server and pass Japanese strings:
Code Snippet(VC++ 6.0):
cin >> str;
cout << str << endl;
Note: here, input is U+307E,U+305B and U+3093.
The above program runs fine with chars and cin/cout/scanf/printf, in fact
things go weird when I use wchars and wcin/wcout/wscanf/wprintf, it just
doesn't output anything!
How/Why is cin/cout/scanf/printf able to process Japanese strings on a
Japanese machine with a char, and not wcin/wcout/wscanf/wprintf with wchar?
Isn't that wchars/wide methods are needed for chars beyond the 8-bit range
as char can't handle it? Am I missing something here?
Thanks in advance.
