I've seen this problem before ( another post ) longish time ago.. I then had thought I had about 50% solution, then the issue seemed to be forgotten.. at one of my test elgg sites (hrea.ensci.us) - you can see the same diamond question marks. That came from ( I 1/2 forget ) from something I cut/paste from some file emailed to me. On the original document, the chars look ok, but when cut/paste into the html -- boom !!! I left the funny chars there to remind myself to look into this later...

Those chars are usually caused by an encoding mismatch..

What text editor are you using? Can you check the document type?

Try saving the page as UTF-8 and see if they don't go away.. Those little marks may be what are called boms..

Looking at my lists of pages I'd say they were listed in reverse alphabetical order. Hard to sort that anyway except by some planning during the creation stage or renaming them bearing this in mind.
