Description:
------------
Passing UTF-8 encoded text with Japanese characters to imagettftext() produces incorrect output. Works correctly on my Ubuntu 7.10 machine, but broken on FreeBSD 6.3, web server.

Reproduce code:
---------------
mb_language('uni');
mb_internal_encoding('UTF-8');

header('Content-type: image/gif');

$text = '日本語';  //Japanese text
$font = './Cyberbit.ttf';

// Create the image
$im = imagecreatetruecolor(160, 160);
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);

// Create some colors
imagefilledrectangle($im, 0, 0, 159, 159, $white);

// Add the text
imagettftext($im, 12, 0, 20, 20, $black, $font, $text);
imagegif($im);
imagedestroy($im);


Expected result:
----------------
Copy of correct image from my local machine: http://www.ibeni.net/flashcards/imagetest.php.gif

Copy of phpinfo() from my local machine: http://www.ibeni.net/flashcards/phpinfo.php.html

Actual result:
--------------
Broken Image on web server: http://www.ibeni.net/flashcards/imagetest.php

Copy of phpinfo() from my webhost server: http://example5.nfshost.com/phpinfo

I see that bug submission forum has "helpfully" encoded the Japanese text in my code into HTML entities ('日本語'). In my original code, the text is encoded directly in UTF-8 _not_ HTML entities.

Make sure your font supports the characters

Does this issue still persist with current PHP/GD versions?
