font oddity on OS X

[Mark Moll]

I observed the following odd behavior with a freshly compiled emacs 
from CVS. I have the code below in my .emacs to set it up for a mac 
keyboard. The odd thing is that if I press "option-u u" for instance, I 
get "¸" instead of "ü". Similarly, "option-e e" produces "È" instead of 
"é". Bizarrely, the problem goes away if I press "option-shift-minus" 
(em dash) once.

(set-terminal-coding-system 'iso-8859-1)
(set-language-environment "Latin-1")
(set-keyboard-coding-system 'mac-roman)
(set-selection-coding-system 'mac-roman)
(setq mac-keyboard-text-encoding kTextEncodingISOLatin1
      mac-command-key-is-meta t
      mac-emulate-three-button-mouse t)
(set-frame-font "fontset-mac")
