Dreamweaver CS5 inserts unexpected Diamond character

Question

When I Alt-tab from a Dreamweaver CS5 webpage to switch to another application (in Windows 7), occasionally an unexpected character is inserted in the HTML page.  It has source code &diams; and appears as the diamond character.  I can't understand why this happens, and only intermittently.  My pages have the meta directive <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />.
Any ideas?
Thank you,

You can get away with using
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
as the charset encoding.
This will not affect how your code functions in non-unicode aware software. This is a directive for browsers to render your page using UTF-8.
If you're still skeptical to do this, open your webpage in any browser the way it is (with ISO-8859-1) and go to View > Character Encoding > Set UTF-8 to see how the browser loads the page then. If all looks well, you can safely change the encoding type in your meta directive to UTF-8 charset.
