unicode文件处理

1.unicode文件的打开必须用rb模式。

3.wchar_t str[100] = { 0 }; 这个占200个字节。

2.宽字符对应的处理

• fgetc fgetwc
• fputc fputwc
• fgets fgetws
• fputs fputws
• fprintf fwprintf
• fscanf fwscanf
• fread ,fwrite

3.操作：

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
#include <stdlib.h>
#include<locale.h>

void main1()
{

    FILE *pf = fopen("C:\\Users\\yincheng01\\Desktop\\QQ-腾讯通讯录.txt", "rb");
    while (!feof(pf))
    {
        char ch = fgetc(pf);
        putchar(ch);

    }
    fclose(pf);

    system("pause");
}

void main2()
{
    setlocale(LC_ALL, "zh-CN");
    FILE *pfr = _wfopen(L"C:\\Users\\yincheng01\\Desktop\\QQ-腾讯通讯录.txt", L"rb");
    FILE *pfw = _wfopen(L"C:\\Users\\yincheng01\\Desktop\\QQc.txt", L"wb");
    while (!feof(pfr))
    {
        wchar_t ch = fgetwc(pfr);//获取宽字符
        fputwc(ch, pfw);
        putwchar(ch);//显示宽字符

    }
    fclose(pfr);
    fclose(pfw);
    system("C:\\Users\\yincheng01\\Desktop\\QQc.txt");

    system("pause");
}

void main3()
{
    setlocale(LC_ALL, "zh-CN");
    FILE *pfr = _wfopen(L"C:\\Users\\yincheng01\\Desktop\\QQ-腾讯通讯录.txt", L"rb");
    FILE *pfw = _wfopen(L"C:\\Users\\yincheng01\\Desktop\\QQ.txt", L"wb");
    while (!feof(pfr))
    {
        wchar_t wstr[256] = { 0 };
        fgetws(wstr, 256, pfr);
        wprintf(L"%ls",wstr);
        fputws(wstr, pfw);//宽字符写入

    }
    fclose(pfr);
    fclose(pfw);
    system("C:\\Users\\yincheng01\\Desktop\\QQ.txt");
    system("pause");
}

void main()
{
    setlocale(LC_ALL, "zh-CN");
    //wprintf(L"%s", L"hello天朝");
    wchar_t wstr[100] = { 0 };
    fwscanf(stdin, L"%s", wstr);
    fwprintf(stdout, L"%s%d%s", L"海华", 100,wstr);

    system("pause");
}
