All right. So how do I fix it? I can't publish a graph with a box in place of the Greek letter that's supposed to label its axis. Can I cut out the box somehow and substitute a Symbol letter from the PSE font list? How do I change my PSE prefs to allow it to substitute? A misleading and error prone substitution would be better than a box. Surely I don't have to go back to OS 10.7, or do I?
