How can I print unicode codepoint as unicode character in C++ (gcc/clang) on Linux? Let say I have something like this:
typedef uint32_t codepoint;
codepoint cp = somefunction();
How can I print cp as single unicode character? I have en_US.UTF-8 locale.
I've searched SO, I've tried: wcout, wstring, wchar_t, setlocale, codecvt (no existent in gcc).
std::wcout
in GNU has a little quirk : while synchronized with C stdio, both C++ and CI/O subsystems need to be localized separately:
so either unsync
#include <iostream>
#include <cstdint>
#include <locale>
int main()
{
std::uint32_t n = 0x98A8;
std::wcout.sync_with_stdio(false);
std::wcout.imbue(std::locale("en_US.utf8"));
std::wcout << wchar_t(n) << '\n';
}

or localize both
#include <iostream>
#include <cstdint>
#include <locale>
#include <clocale>
int main()
{
std::uint32_t n = 0x98A8;
std::setlocale(LC_ALL, "en_US.utf8");
std::wcout.imbue(std::locale("en_US.utf8"));
std::wcout << wchar_t(n) << '\n';
}
