I'd like to fix this.

Do you know why it works from terminal?  Is there some code in emacs  
that reads the LANG or some other env setting and sets something in  
emacs?  Where?  What is the command to set the language environment?

While the various methods on the net to set up ~/.MacOSX/ 
environment.plist might work, there ought to be some Cocoa way to  
detect language setting directly...
