    Writing to files problem, file created is octet-stream and not text

    I'm trying to write to files with fprintf, here are some examples:

    FILE *fp;
    fp = fopen("teste.txt", "w")
    fprintf(fp, "# Author: %s\n", author);
    however, if author, for instance, has some chars like or even , the text file will not be saved correctly. Why?

    Easy to fix? How?

    works for me using VC++ 6.0
    #include <stdio.h>
    int main(int argc, char* argv[])
    	FILE* fp = fopen("myfile.txt","w");
    	fprintf(fp,"%s\n","   or even ,  ");
    	return 0;
    below also works
    	char author[] = "   or even ,  ";

    After testing this a bit more I found something...
    First, I'm compiling this on linux using gcc of course...

    Files with special chars saved in .txt extension -> work fines, they are text files

    Files with special chars saved in other extension -> file is not a text file but if I open it in a text editor I see all the text just as I see when I save it with .txt extension

    Files with or without special chars -> work fine and they are text files

    so the, problem is, when I save a file with those special chars with a different extension than .txt, however, I need it to be just text (and it is) but to save it in a different extension. that seems to be my problem.

    When I go the file properties, I see there on the mime type: application/octet-stream instead of text/plain.

    no one knows why? It would be nice if I could fix this in the next 12 hours, I'll then have to present the whole project to my teachers...
