In /template/default/settings.tpl, create a new option for your preferred locale as follows

<option value="lo_LO lo_LO.CHARSET-1 lo_LO.CHARSET-2 ...">

No, it doesn't. But you can fix this.

In /template/default/header.tpl and /template/default/preview.tpl, change the charset's value of the Content-Type meta tag to UTF-8.

In functions.php, look for function getZoneDate() around line 56 and replace the return line with this code

return utf8_encode(
    gmstrftime($format, $time + $this->configs['zone']*3600));

In the page where the calendar is included, create a style element *after* linking to the calendar's style sheet as following:

<style type="text/css">
#calendar .calendarDetail .calendarEvent {
	margin:0 0 0 -180px;
}
</style>

Modify the *.tpl and *.css files in "/template/default/" directory.

If you're sure that you have GD2 installed then it's because of wrong document root setting. Set your document root manually as following.

<?php
...
$gallery = new WingedGallery();
...
$gallery->setDocumentRoot('/YOUR/DOCUMENT/ROOT');
...
?>
