    how can i read a unicode char from a file ?

    when i save a file as Unicode every char will be 2-byte long

    how can i read it from a file ??

    if i use for example

    Code:
    FILE *fp;
    c = getc(fp)
    the c will contain a one byte ??
    because i get it a character by character and long of the character just one byte !!!!!!!!!

    i want to read the character so it will be 2 byte

    cuz i want the program take the char as Unicode and convert it to something like ISO or Cp .. etc

    there is an error when i use fread() , here`s the problem

    Code:
    #include<stdio.h>
    #include<stdlib.h>
    #include<string.h>
    
    int main(int argc,char *argv[])
    {
    
    	FILE *out;
    	FILE *in;
    	wchar_t *ch;
    
        if((ch=(wchar_t *)malloc(sizeof(wchar_t))) == NULL)
        {
            printf("Error: No enough memory\n");
            getchar();
            return 1;
        }
    	in = fopen("test.txt","rb");
    	out = fopen("output.txt","wb");
    	if(in == NULL)
    	{
    		printf("Can`t open file:%s\n",argv[1]);
    		exit(0);
    	}
    
    	while(fread(ch,sizeof(wchar_t),1,in) > 0)
    	{
    		printf("%d\n",ch);
    		fwrite(ch,sizeof(wchar_t),1,out);
    	}
    
    	fclose(in);
    	fclose(out);
    	return 0;
    }
    test.txt include the char
    Code:
    ب
    and if i read it and printf it using :
    Code:
    printf("%d\n",ch);
    it output this number :
    2824864
    why ??

    i am sure that the char
    Code:
    ب
    in unicode equal to 1576

    so the question is
    how could i print out the unicode decimal value of a char in a unicode text file ?

    There are wide equivalents of most things in C99.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
