Hi Rich
Sorry. I managed to solve the problem. You were right.
Of course, there are only some minor problems regarding that string literals
do not match exactly with those strings read from a file, thus string
comparison functions fail to operate. I am going to investigate on it.
Thanks a lot
Best Regards

Hello Rich
Sorry, again.
I wrote a simple C program using your guidelines but unfortunately it does
not work well:
The program is as follows:
#include <stdio.h>
#include <errno.h>
#include <stdlib.h>
#include <string.h>
#include <locale.h>
#include <langinfo.h>
int main (
int argc,
char *argv[]
)
{
FILE *input_file;
char buffer[1024];
if (!setlocale (LC_CTYPE, ""))
{
fprintf (stderr, "Locale not specified. Check LC_ALL,
LC_CTYPE or LANG.\n");
return EXIT_FAILURE;
}
if (!(input_file = fopen ("./in.txt", "r")))
{
fprintf (stderr, "Could not open file : %s\n", strerror
(errno));
return EXIT_FAILURE;
}
fgets (buffer, sizeof (buffer), input_file);
fprintf (stdout, "%s", buffer);
return EXIT_SUCCESS;
}
The program does not print the line read from the file to stdout (some
junks are printed). I also used "cat ./persian.txt | iconv -t utf-8 >
in.txt" to produce a UTF-8 oriented file.
Best Regards
Ali
