在C中打印Unicode符号 [英] Printing a Unicode Symbol in C
问题描述
我正在尝试打印Unicode星号( 0x2605 )在使用C的linux终端中.我遵循了网站上其他答案所建议的语法,但是没有得到输出:
I'm trying to print a unicode star character (0x2605) in a linux terminal using C. I've followed the syntax suggested by other answers on the site, but I'm not getting an output:
#include <stdio.h>
#include <wchar.h>
int main(){
wchar_t star = 0x2605;
wprintf(L"%c\n", star);
return 0;
}
我希望您能提出任何建议,尤其是如何使用ncurses
库来完成这项工作.
I'd appreciate any suggestions, especially how I can make this work with the ncurses
library.
推荐答案
两个问题:首先,必须以%lc
格式而不是%c
打印wchar_t
.第二个问题是,除非调用setlocale
,否则字符集设置不正确,并且可能会得到?
而不是星号.但是,以下代码似乎可以正常工作:
Two problems: first of all, a wchar_t
must be printed with %lc
format, not %c
. The second one is that unless you call setlocale
the character set is not set properly, and you probably get ?
instead of your star. The following code seems to work though:
#include <stdio.h>
#include <wchar.h>
#include <locale.h>
int main() {
setlocale(LC_CTYPE, "");
wchar_t star = 0x2605;
wprintf(L"%lc\n", star);
}
