How Can I Correctly Print Unicode Characters in C ?

Printing Unicode Characters in C

When attempting to print a character with a Unicode value, such as Cyrillic Small Letter Ef (U 0444), the following code may not work as expected:

int main() {
   wchar_t f = '1060';
   cout <p><strong>Solution:</strong></p><p>To print Unicode characters correctly, there are several methods:</p>

• Universal Character Names (UCNs):

  • The character 'ф' can be represented as 'u0444' or 'U00000444'.

• Literal Characters (if supported by source encoding):

  • If the source code encoding supports the character, it can be written directly as 'ф'.

For terminal printing, the following code assumes compatibility between the execution encoding and the terminal emulator:

#include <iostream>

int main() {
    std::cout <p>For Windows, setting the output file handle to UTF-16 mode is recommended:</p>
<pre class="brush:php;toolbar:false">#include <iostream>
#include <io.h>
#include <fcntl.h>

int main() {
    _setmode(_fileno(stdout), _O_U16TEXT);
    std::wcout <p>For portable code, the following technique can be used:</p>
<pre class="brush:php;toolbar:false">#include <iostream>
#include <vector>

int main() {
    std::vector<wchar_t> v = {0x444};
    std::wcout.write((const wchar_t*)&v[0], 1);
}</wchar_t></vector></iostream>
