Newscalendar

In some cases, the following weird characters are prepended to the (x)html code of the pages including newscalendar:



The characters are displayed at the top of the page, spoiling the layout.
That sequence of characters is known as "BOM marker":

The sequence is actually at the beginning of some templates and files belonging to the extension, probably due to an editor that has included the marker when saving:

• res/listViewTemplate.html
• res/bt-0.9.5-rc1/other_libs/jquery.hoverIntent.minified.js
• hooks/class.tx_newscalendar_additionalMarkers.php

The problem is easily fixed just by removing the marker, using the script provided at the URL above.
