I can confirm this on my other Mac (Snow Leopard), and can't say on the 
spot how I managed before on the one running Leopard.

For some reason, Proof General 4.1 tries hard to ignore the IsabelleText 
default font.  There is a specific font selection menu "Tokens -- Set Font 
-- Symbol" etc.  Even if everything is set to "IsabelleText", Emacs uses 
odd default fonts that lack some unicode glyphs.
