extended ascii and display locale

locale.c

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

int main() {
	// Set the locale to the user's default locale
    setlocale(LC_ALL, "");  
	
	// wchat_t is a wide character type
    wchar_t c1 = L'ò';
	wchar_t c2 = L'¡';
	  
	// %lc is the format specifier for a wide character  
    wprintf(L"%lc %lc\n", c1, c2);
    return 0;
}

locale2.c

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

int main() {
    // Set the locale to the user's default locale
    setlocale(LC_ALL, "");  
//print the locale
	wprintf(L"Locale is: %s\n", setlocale(LC_ALL, ""));
    for (int i = 128; i <= 255; i++) {
        wchar_t c = (wchar_t)i;
		//starts printing anything recognizable from the 161th character
        wprintf(L"%lc ", c);
    }
    wprintf(L"\n");
    return 0;
}

the first would print the chars ò ¡ WITHOUT using unicode, only extended ascii... I believe.
And trying to print from 128 to 255 I get these chars according to my locale.
¡ ¢ £ ¤ ¥ ¦ § ¨ © ª « ¬ ® ¯ ° ± ² ³ ´ µ ¶ · ¸ ¹ º » ¼ ½ ¾ ¿ À Á Â Ã Ä Å Æ Ç È É Ê Ë Ì Í Î Ï Ð Ñ Ò Ó Ô Õ Ö × Ø Ù Ú Û Ü Ý Þ ß à á â ã ä å æ ç è é ê ë ì í î ï ð ñ ò ó ô õ ö ÷ ø ù ú û ü ý þ ÿ
And to set the locale. Interestingly for those doing minishell, it is set as an environmental variable in bash! Like
export LC_ALL=en_US.UTF-8
It is using UTF-8 behind the scenes?
locale -a Would list the available locale. I tried of course export LC_ALL=ja_JP.eucJP but my terminal did not like it...
