UTF-8 Decoder

Task

In the file decode2.c with a main function that reads a line from the user. It should assume there are at least two bytes of standard input, and that the first two bytes are a 2-byte UTF-8 encoded character. The program should print the code point of that character in decimal format.

1. Create your program in decode2.c
2. Then use your program to calculate the code point for "ɽ" and save it in the file codepoint.txt. You may want to copy-paste it into the terminal to give it as input to your program. Here it is on its own line to make copy-pasting easy:
   • ɽ

---

Example

$ gcc decode2.c -o decode2
$ ./decode2
ɒ      # this line is the typed input (probably copy-paste from the question)
594    # this line is the output you should save to codepoint.txt

---

Code

#include <stdio.h>
 
int main(int argc, char** argv){
    char buffer[3];
    fgets(buffer, sizeof(buffer), stdin);
 
    int codepoint = ((buffer[0] & 0x1F) << 6) + (buffer[1] & 0x3F);
 
    printf("%d\n", codepoint);
}
