bug#6024: 23.1; MacOS X (10.5.8); Unicode fonts not displayed well


From: Michael Norrish
Subject: bug#6024: 23.1; MacOS X (10.5.8); Unicode fonts not displayed well

User-agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.9) Gecko/20100317 Thunderbird/3.0.4

Though I know the font has a Greek alpha (U+03B1) and beta (by looking at the "Character palette" tool), emacs fails to display it, even though it's happy to display a collection of mathematical arrows. The universal quantifier (U+2200) is odd too; though it's there, it's enclosed in a little box. I suspect that's spurious, though I've no idea how I induced the box to appear. (See the attached screenshot.)

(The only fonts I could find that would display the Greek letters were Helvetica and Times.

I confirmed with M-x describe-char that the characters were actually there, and just not displayed.

The emacs was started as

  Applications/Emacs.app/Contents/MacOS/Emacs -q
