Enabled Tibetan keyboards -- all good
Slowly added back Tibetan fonts as directed -- all good
Made a test ID document in Tibetan -- still all good!
Sooo - good news is that everything's working again. bad news is that I don't know why. I think I will just proceed to work carefully, and if the problem arises again, try to note which font and other variables were in recent play... w
Thanks again, Peter and Joel.
Best,
Claire
