2. The display of Greek is off. The default font won't display accented

characters at all.  The font I've been using,

-apple-monaco-medium-r-normal--12-120-72-72-m-120-iso10646-1, does display all of the characters, but the accented ones are a different size, and the

Greek in general looks like a comic book.

Hmm.  With M-x view-hello-file, I can see them (in Monaco).

Switching to text-mode will make it use Lucida Grande (the default), but, as shown below, this works for me. I started Aquamacs with -q (e.g., see Help->Diagnose menu). Could you try that too, just so we make sure we're talking about the same "default font"?

As for the actual glyphs and also the accented alpha in the example, I fully agree: they're ugly, both in Monaco and in Lucida.

I think there's something wrong... I'm attaching a screenshot of Emacs/22 (Carbon), where the greek glyphs are rendered coherently.

The last screenshot shows Emacs 23 (NS) again, started with -Q and in the default font. There, the accented alpha isn't rendered at all.
