ASCII->UNICODE

Hello,
I friend of mine has a homework, but can't do it at all. So I decided to post it here. So, he must do a C program that converts ASCII to UNICODE files incl. Bulgarian language. I googled for it, but can't find anything. Actually I don't want the full code, but I need only some piece of code that do the converting.

Best regards!

Unicode is an abstract mapping of integers to symbols. It is not a character encoding. You need a character encoding.

Here is what I found:

* Convert ASCII to Unicode since all data is saved as Unicode.
275 */
276 static void PROPSHEET_AtoW(LPCWSTR *tostr, LPCSTR frstr)
277 {
278 INT len;
279 WCHAR *to;
280
281 TRACE("<%s>\n", frstr);
282 len = MultiByteToWideChar(CP_ACP, 0, frstr, -1, 0, 0);
283 to = Alloc(len * sizeof(WCHAR));
284 MultiByteToWideChar(CP_ACP, 0, frstr, -1, to, len);
285 *tostr = to;
286 }

Hi again,
I did the program, but now I have another problem. It outputs me only the first 5 chars of the sentence and didn't output the Cyrillic. Here is the code if somebody can help:

#include <stdio.h>
#include <string.h>
#include <wchar.h>
#include "convert.h"

bool AsciiToUnicode(const char * szAscii, wchar_t * szUnicode)


{
int len, i;
if((szUnicode == NULL) || (szAscii == NULL))
return false;
len = strlen(szAscii);

for(i=0;i<len+1;i++)
*szUnicode++ = static_cast<wchar_t>(*szAscii++);
return true;
}

int main()
{
FILE *f;
char s[1000];
wchar_t rch;
f=fopen("C:\\a.txt","r");
if (!f)
return 1;
while (fgets(s,1000,f)!=NULL)
{
if(AsciiToUnicode(s, &rch))
printf("Not testing:%ls\n", &rch);
else printf("Testing:%s\n", s);
}
fclose(f);
return 0;
}

... and here is Convert.h:

#ifndef CHARSET_CONVERSION
#define CHARSET_CONVERSION
#include <stddef.h>
bool AsciiToUnicode(const char * szAscii, wchar_t * szUnicode);
bool UnicodeToAscii(const wchar_t * szUnicode, char * szAscii);
#endif

Best regards!

I change the function AsciiToUnicode to:

wchar_t* ASCIIToUnicode(const char *ascii )
{
//first it would be best to discover where the '\0' is located
int i, length;
length = strlen(ascii);
for(i=0;i<length;++i)
{
if(ascii[i]=='\0')
break;
}
++i;
//now we can make the actual Unicode array
char *unicode = (char*)calloc(i,sizeof(wchar_t));
// if(unicode==NULL)
// return 1;
for(int j=0;j<i;++j)
{
unicode[j*2]=ascii[j];
unicode[j*2+1]='\0';
}
return (wchar_t*)unicode;
}

Now it prints out all, but the Cyrillic shows with hieroglyphs

Can anybody help? It is urgent ,,,
