Here's an idea: improve the handling of .dir-locals.el so that it could 
contain something like this:

  ((nil . ((coding . 'utf-8)
       (tab-width . 8)
       (fill-column . 70)))
   (c-mode . ((c-file-style . "GNU"))))

This specification for "coding" would take precedence over coding 
inferred from environment settings.  It would not take precedence over 
an explicit coding cookie in the file.

Currently .dir-locals.el cannot specify 'coding', but I suspect that's 
mostly just due to the intricacies of the current implementation, not 
due to any specific desire to reject the use of 'coding' in .dir-locals.el.
