Locale handling is done in sscanf (glibc).

Exactly.

setlocale( ,"") tells libc to use the locale which the user has
requested for this process. That is the correct thing to do.

Why?  It's the user's .Xdefaults file.  He should construct
it to be consistent with his chosen locale.  

But if you want gnuplot_x11 always to run in a specific locale,
you can make a wrapper script:

gnuplot_x11:
	#!/bin/csh
	setenv LC_TYPE C
	real_gnuplot_x11 $@
