Sorry, Noreen, I started my post before you described what you see. I am curious about your OS and browser though. Still, the boxes you describe suggest that you may not have a font that contains a schwa character. Another possibility is that your OS doesn't support Unicode character sets.

‘38’ isn't a font specification. In the example, I coded the leading ampersand as & so it wouldn't be seen by browsers as a valid character code. I wanted to show the coding without having it interpreted.
