cout, cin etc. question [message #15235]

Does U++ library contain stdout, stdin, stderr as FileStream classes?

If not, then how to use the U++ classes to do stdin/out via Stream classes in order to use proper charset (e.g. WIDE char under WinXP) because standard library (in case of MSVC) uses ANSI charset for cin, cout?

Thanks in advance!

Cout()
Cerr()

instead of Cin stream, there is

String ReadStdIn();

(reads single input line).

Oh, actually, I did not even knew that you can do or bother with UNICODE in console... Smile

Well, actually unicode in console is a very rare use case. It is just related to the bug report I posted about command line arguments being not unicode and I wanted to print it to the console and thus found out that console output is not unicode aware as well Smile

So I don't think it is of great importance.

In Windows, the console can be relatively easily Unicode-aware under an NT-derived OS.

Instead of std::cout/std::cin/std::cerr, you'd use std::wcout/std::wcin/std::wcerr.

Typically, I like to have some header file with something like the following:

#ifdef UNICODE
#define Tcout std::wcout
#define Tcin std::wcin
#define Tcerr std::wcerr
#else // UNICODE
#define Tcout std::cout
#define Tcin std::cin
#define Tcerr std::cerr
#endif // UNICODE

In this way, I can use the standard stream classes for working with TCHARs (again, in Windows). I've done this with a number of console applications in the past.

I don't know as much about U++ in these regards, though.
