Some characters are replaced by question marks!
For example, on internet, look up a word "pediment" in Yahoo! Dictionary ( http://education.yahoo.com/reference/dictionary/entry/pediment)... Instead of showing the "dot" symbol to identify a syllabus break, it shows question marks as ped?i?ment, and instead of showing c with a little squiggle underneath for a word facade (within the definition of pediment), it shows fa?ade.
I did not have this problem on my iMac on Tuesday (01/29/08) morning and I have not installed anything other than the Apple updates.
I tried with FireFox and Safari, and both show the same thing. Then I went and checked my husband's iMac (OS X 10.5.1 Leopard) and it has a same problem, so I know it is not just my iMac.
Then (yes, there is more...) I started to work on my Word document and tried to insert "symbol" from insert on the Toolbar... many of my symbol fonts (Symbol, Osaka, etc) has question marks replacing special characters.
Please help! I am unable to complete my work without these special characters!!
iMac, Mac OS X (10.5.1), Corrupt font files from updates?
