Go4Expert - multi byte to wide char converting problem(Related to Unicode)

Hi,

I prepared this program please go through it. i am running this program in linux with gcc compiler. i am giving input in the tmp.txt file with Telugu or Hindi characters.

But I am not getting proper output. I found 2 problems:
1. These characters are not converting to wide characters.
2. On the console characters are printing with some junk value.

Can any one help me to solve.

PHP Code:


		
			
#include<stdio.h>

#include<wchar.h>



void convertMultiBytes(wchar_t *wchar, char *mbyte);



main()

{

FILE *fp;

wchar_t *aa;

char c[100];

int l=0;

if((fp=fopen("tmp.txt", "r")) == NULL) {

    printf("Cannot open file.\n");

    exit(1);

  }

fgets(c,25,fp);

l=strlen(c);

printf("%d",l);

aa=(wchar_t *)malloc((l+1)*4);

memset (aa, 0, (l + 1)*4);

convertMultiBytes(aa,c);

printf("Entered maultybyte string:%s\nConveted wild char string:%ls\n",c,aa);

}





void convertMultiBytes(wchar_t *wchar, char *mbyte)

{

   int n;

   char *end,*start;

   n = strlen(mbyte) + 1;

   /* convert multibyte string to wide character string */

   if (mbstowcs(wchar,mbyte,n) == (size_t)-1)

   {

       printf("ERROR: Could not convert multibyte character to wide char code\n");

       convertBytebyByte(wchar,mbyte,n);

   }

}

void convertBytebyByte(wchar_t *wchar, char *mbyte, int n)

{

   int mbcnt;

   char *end,*start;

   end = mbyte + n;

   start = mbyte;



   for(;start <= end;)

   {

       mbcnt = mbtowc(wchar,start,20);

       if(mbcnt > 0)

       {

           start += mbcnt;

           wchar++;

       }

       else

       {

           printf("Invalid multibyte character occured\n");

           printf("Converting the invalid character to '?'\n");

           *wchar = '?';

           start++;

       }

   }

}
