Write to text file - wrong character encoding?

I'm trying to write to a text file, and keep getting this error message:

gedit has not been able to detect the character encoding.
Please check that you are not trying to open a binary file.
Select a character encoding from the menu and try again.

void write_maze(char *filename, char *maze, int rows, int cols)
{
	ofstream solved (filename);
	if (! solved.is_open()){
		cout << "Failed to open " << filename << endl;
	}
  solved << rows << " " << cols;
	for (int i = 0; i <= (rows * cols); i++) {
		solved << maze[i];
		if (! ((i + 1) % cols)) {
			solved << endl;
		}
	}
  solved.close();
}


What am I doing wrong? It was working earlier with a very basic file, but that didn't suit my purposes.

Are you sure you should be using <= and not < on line 8?
Check the file really is text and as you think it should be with the command
cat filename
at the command line.
You win, Peter. I've been changing my code so much for the last 8 hours, little details are slipping my mind. Thank you
