How to printing text on image in PHP for characters beyond ascii 127?

I am using the PHP GD library API - imaget开发者_高级运维tftext, to print texts on images. I am trying to print the left and right double quotes (i.e. ones with HTML entities “ and ”) on it. As per the documentation I print the text '“' for “.

On my local system it works, but not on my production server. On server I am running:-

PHP 5.3.7 (cli) (built: Aug 18 2011 19:02:25)
Copyright (c) 1997-2011 The PHP Group

Seeme like an obvious character set issue. Checkout http://www.php.net/manual/en/intro.iconv.php for more info, but i would assume your issue would be resolved by changing your iconv.internal_encoding to something that supports your characters.

iconv_set_encoding("internal_encoding", "UTF-8");

I'd give that a shot ;)
