How Can I Print Unicode Characters in C ?

Printing Unicode Characters in C

Printing Unicode characters in C can seem like a daunting task. However, it is actually quite straightforward once you understand the concept.

To print the Russian character "ф" (U 0444), you can use Universal Character Names (UCNs). UCNs assign a unique identifier to each Unicode character. For instance, the UCN for "ф" is "u0444".

Here is an example of how to print "ф" using UCNs:

#include <iostream>

int main() {
    std::cout << "\u0444" << std::endl;
}

If your source code supports the character, you can also use the literal representation of the character:

#include <iostream>

int main() {
    char f = 'ф';
    std::cout << f << std::endl;
}

Additionally, if your console encoding supports the character, you can print it directly using the standard output stream:

#include <iostream>

int main() {
    std::cout << "Hello, ф!" << std::endl;
}

Printing Unicode characters can be slightly more complex in Windows environments. To ensure proper display, you may need to set the mode of the output file handle to accept UTF-16 data:

#include <iostream>
#include <io.h>
#include <fcntl.h>

int main() {
    _setmode(_fileno(stdout), _O_U16TEXT);
    std::wcout << L"Hello, ф!" << std::endl;
}

Remember that portable code may require a different approach.
