EXAMPLES
       Example #1

	      mb_output_handler(3) example

	      <?php
	      mb_http_output("UTF-8");
	      ob_start("mb_output_handler");
	      ?>

NOTES
       Note

	       If  you	want to output binary data, such as an image, using PHP 4.3.0 or later, a Content-Type: header must be set using header(3)
	      before any binary data is sent to the client (e.g. header("Content-Type: image/png")). If Content-Type: header is sent, output char-
	      acter encoding conversion will not be performed.

	       Note that if 'Content-Type: text/*' is sent, the content body is regarded as text; conversion will take place.

	       If  you	want  to  output  binary  data, such as an image, using PHP 4.2.x or earlier, you must set output encoding to "pass" using
	      mb_http_output(3).
