c - 在C中打印UTF-8多字节字符

Question

我编写此代码是为了打印 UTF-8 多字节字符串。但它无法正确打印。注意:我是在Linux系统中进行的。

#include <stdio.h>
#include <locale.h>

int main()
{
    char *locale = setlocale(LC_ALL, "");
    printf("\n locale =%s\n", locale);
    printf("test\n \x263a\x263b Hello from C\n", locale);

    return 0;
}

Answer 1

使用\u代替\x:

#include <stdio.h>
#include <locale.h>

int main()
{
    char *locale = setlocale(LC_ALL, "");
    printf("\n locale =%s\n", locale);
    printf("test\n \u263a\u263b Hello from C\n");

    return 0;
}

它运行并产生以下输出:

$ gcc foo.c
$ ./a.out 

 locale =C
test
 ☺☻ Hello from C
