如何读/写UTF8的文本文件用C？ [英] How to Read/Write UTF8 text files in C?

问题描述

我试图读取文本文件文本UTF8，然后打印一些它到另一个文件。我使用Linux和gcc编译器。这是code，我使用：

i am trying to read UTF8 text from a text file, and then print some of it to another file. I am using Linux and gcc compiler. This is the code i am using:

#include <stdio.h>
#include <stdlib.h>

int main(){
    FILE *fin;
    FILE *fout;
    int character;
    fin=fopen("in.txt", "r");
    fout=fopen("out.txt","w");
    while((character=fgetc(fin))!=EOF){
        putchar(character); // It displays the right character (UTF8) in the terminal
        fprintf(fout,"%c ",character); // It displays weird characters in the file
    }
    fclose(fin);
    fclose(fout);
    printf("\nFile has been created...\n");
    return 0;
}

它适用于英文字符现在。

It works for English characters for now.

推荐答案

这code为我工作：

/* fgetwc example */
#include <stdio.h>
#include <wchar.h>
#include <stdlib.h>
#include <locale.h>
int main ()
{
  setlocale(LC_ALL, "en_US.UTF-8");
  FILE * fin;
  FILE * fout;
  wint_t wc;
  fin=fopen ("in.txt","r");
  fout=fopen("out.txt","w");
  while((wc=fgetwc(fin))!=WEOF){
        // work with: "wc"
  }
  fclose(fin);
  fclose(fout);
  printf("File has been created...\n");
  return 0;
}
