比较字符串和包含土耳其语字符的用户输入时，strcmp函数不起作用

Question

char *x="Çankırı";
char *y=malloc(sizeof(char)*25);
scanf("%s",y);

if(strcmp(x,y) == 0)
    printf("A");
else
    printf("%s",y);

I enter 'Çankırı' for y, but else part runs. How can I compare these strings?

Windows10 , codeblocks.

EDIT: I found a clue. Problem is about setlocale function. When I use setlocale(LC_ALL,"TURKISH"), one of the string doesn't work fine(Output is not Çankırı, Ank2r2), and If I use setlocale(LC_ALL,"C"), other one doens't work fine. I don't know how to fix it.

You probably need to use functions that accept 'wide' characters. For example:

#include <wchar.h>
wchar_t *x=L"Çankırı";
wchar_t y[25];
wscanf(L"%s",y);

if(wcscmp(x,y) == 0)
    wprintf(L"A");
else
    wprintf(L"%s",y);
