File does not read UTF-8 input in C

Question

I have this code:

#include <stdio.h>
#define SIZE 100

int main(void) {

   char myWord[SIZE];

   printf("Enter \"blå\": ");
   fgets(myWord, sizeof(myWord), stdin);
   printf("Entered string: %s", myWord);

   return 0;
}

And this is my output:

Enter "blå": blå
Entered string: bl

Why doesn't fgets properly read the input? I changed the character encoding to UTF-8 using this guide:

Using UTF-8 Encoding (CHCP 65001) in Command Prompt / Windows Powershell (Windows 10)

This helped me print blå instead of bl├Ñ but I still can't read input from the user. The only solution I can think of is that I need to change the encoding of stdin. Do I do that with locale.h or is there another way?

I am on windows and VScode and have MINGW32 as compiler.

Works correctly in bash, so it appears to be your terminal encoding. — stark, Jul 01 '23 at 15:48
If I enter chcp then the output is "Active code page: 65001". Doesn't this mean that UTF-8 is enabled? — Alexander Jonsson, Jul 01 '23 at 16:27
@Alexander Jonsson, when debugging such, print the length, use a linefeed and use sentinels. `printf("Entered string: %zu, <%s>\n", strlen(myWord), myWord);`. What was your result? — chux - Reinstate Monica, Jul 01 '23 at 20:09
`fgets()` is fine. See https://stackoverflow.com/a/57134096/1180620 — Mark Adler, Jul 01 '23 at 23:57
@chux - Reinstate Monica Strlen returns 2 and the output is still bl. — Alexander Jonsson, Jul 02 '23 at 11:43
