I am trying to read a csv file and print it. I got what I wanted to do, but I'm not sure how I can print Korean characters

I have a csv file that includes Korean characters. But I am not sure how Korean can be printed in the code that I have.

The csv file looks like this:

name,hp,damage
대학오리,20,5
대학냥이,30,10
시계탑기린,100,20

My code:

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
typedef struct {
char name[1000];
int hp;
int damage;
} Monster;
typedef struct {
char header1[sizeof "name"];
char header2[sizeof "hp"];
char header3[sizeof "damage"];
} Header;
int main()
{
FILE* fp = fopen("entityData.csv", "r");
if (!fp) {
printf("Error opening file\n");
return 1;
}
Monster monsters[100];
int num_records = 0;
char line[100];
Header header;
fgets(line, sizeof line, fp);
strncpy(header.header1, strtok(line, ","), sizeof header.header1);
strncpy(header.header2, strtok(NULL, ","), sizeof header.header2);
strncpy(header.header3, strtok(NULL, "\n"), sizeof header.header3);
while (fgets(line, sizeof(line), fp))
{
char* token = strtok(line, ","); //, 기준으로 나눠서 token에 저장
strncpy(monsters[num_records].name, token, 20);
token = strtok(NULL, ",");
monsters[num_records].hp = atoi(token);
token = strtok(NULL, ",");
monsters[num_records].damage = atoi(token);
num_records++;
}
for (int i = 0; i < num_records; i++)
{
printf("%s:%s %s:%d %s:%d\n",
header.header1, monsters[i].name,
header.header2, monsters[i].hp,
header.header3, monsters[i].damage);
}
fclose(fp);
return 0;
}

The program I wrote reads the csv file above and should print it like this:

name:대학오리 hp:20 damage:5
name:대학냥이 hp:30 damage:10
name:시계탑기린 hp:100 damage:20

Instead the name part is broken.

After some searching around, I realized that Korean letters take up 2 bytes per letter, which does not match char types. I have tried using wchar but that has led to errors, and I feel like that I am stuck.

I know that asking such a question on an English website isn't the best, but I'm really just hoping if anyone knows anything.

There's nothing wrong with your code. It's Windows that's messed up. (It works perfectly fine on Linux and Macs.) Do this to remedy the problem with Windows:

> Enable the new UTF-8 option in Windows settings. Go to the language
> settings, click Administrative language settings, then Change system
> locale… and tick the Beta: Use Unicode UTF-8 for worldwide language
> support option. Restart your computer.

Then languages in UTF-8 will display correctly in terminals.

Yes, the number of bytes can be more than the number of characters. They are likely stored as UTF-8, which encodes each character in one to four bytes. Each of your Korean characters is three bytes (not two). However a comma is still a comma and cannot appear inside another character code, so you would be correctly finding the end of your name string.
