Could be.

Isn't there one already?
Or at any rate a call to setlocale(LC_CTYPE, "")?  
When I enter gnuplot it correctly knows about the locale:

lascaux [1235] ./gnuplot

Terminal type set to 'wxt'
gnuplot> show locale

        LC_CTYPE is en_US.UTF-8
        LC_TIME is C

But we have at least one bug report from somewhere who is having 
trouble getting gnuplot to pull LC_CTYPE from the environment, so I'm
not really sure what is going on.
