    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
