As you maybe aware I use ascii text as my signature in text when posting the gallery.

Wºz™

ALT 0186 = º & ALT0153=™

But when you edit  post I have noticed other unwanted characters being created. Check this image post http://www.renderosity.com/mod/gallery/index.php?image_id=1491668
The issue does not exist with normal threads in forums that I am aware of & the issue has only been apparent since the new site layout has been applied.

Hope someone can fix it :)
