汉字转换Unicode实现

工作需要,实现了一下,在这里记一下学习笔记

/* Filename: ChinesetoUnicode code by:1jjk Email:[e-mail] Compile: gcc -Wall -O2 -g ChinesetoUnicode.c -o ChinesetoUnicode */

{
        FILE *fp;
        int ret=-1;
        char str[1024]={0,};
        wchar_t array[1024]={0,};
        setlocale(LC_ALL, "zh_CN.GBK");

         /*open file*/
        if((fp=fopen("/root/smsconfig.txt","r"))==NULL)

        fclose(fp);

        assert(array);

         /*from chinese to Unicode*/
        if((ret=mbstowcs(array, str, strlen(str)))==-1)
        {

        }
        int i = 0;
        char buf[5] = {0,};
        for(i=0; i<ret; ++i)
        {
        printf("%04X", (int)(array[i]&0xFFFF));
        }

         /*from Unicode to Chinese*/
        if((ret=wcstombs(str,array, strlen(array)))==-1)
        {
                printf("error\n");
        }

        printf("\n %s \n",str);
        return 0;
