ISO to UTF-8 Tutorial

Searching the web for a problem I face on a greek site about encoding, I found a very useful PHP class which changes the charset of a variable.

First of you all you have to download the class from here:
http://mikolajj.republika.pl/files/ConvertCharset/ConvertCharset_v1.0.zip .

Secondly, unzip the file and upload to your /www/ folder the ConvertTables dir and the ConvertCharset.class.php .

Open your php script you want to change the encoding.
Add to the line #1 the next code:

ob_start();
include("ConvertCharset.class.php");
?>

Then, go to the last line of your script and add:

$contents = ob_get_contents(); // store buffer in $contents
ob_end_clean(); // delete output buffer and stop buffering
$FromCharset = "iso-8859-7";
$ToCharset = "utf-8";
$text = new ConvertCharset();
$contents= $text ->Convert($contents, $FromCharset, $ToCharset);
echo "$contents";
?>

Don't forget to change the meta tag charset to UTF-8 to work properly.

Here is the list charsets you can operate with. The main requirement is that a character has to be in both character sets, otherwise it will return an error.
