This is documented in the Emacs info (the "Keyboard and Mouse Input on
Mac" section):

  Emacs recognizes the setting in the Keyboard control panel (Mac OS
  Classic) or the International system preference pane (Mac OS X) and
  supports international and alternative keyboard layouts (e.g.,
  Dvorak) if its script is either Roman, Japanese, Traditional
  Chinese, Korean, Cyrillic, Simplified Chinese, or Central European.
  Keyboard layouts based on Unicode may not work properly.  Selecting
  one of the layouts from the keyboard layout pull-down menu will
  affect how the keys typed on the keyboard are interpreted.

You may want to look at the following documents:
