From my experience the locale problem is related to the internationalization 
of the GTK toolkit, there aren't problems with the text or X11 versions of 
esp-r. To correct the problem when I use the GTK version I issue the command:

export LC_NUMERIC=C

only the locale for  numerics need to be changed.
It is worth noting that this is a common problem for a number of codes also in 
windows , among them GSLedit .
