4.4 - need instructions here on how to do this on Windows. It needs to use a text editor that can handle saving files in UTF-8 format WITHOUT writing the BOM (Byte Order Mark) to the file, which causes odd characters <font style="font-size:200%">ï»¿</font> to appear on TNG pages, and your Admin Menu may display a blank page because there are characters before the <?php which should be first in the file.
4.4.1 - Notepad++
version 5. 1.2 will allow converting the $text variable files to UTF-8 without a BOM.
That's it. Your site should now be running in UTF-8.
