   It also works for me in es_ES.utf8 without the user_preamble.

   I don't know if it's possible to set the locale in the windows script.
   If not, we could force to include "set encoding iso_8859_1" in the
   Gnuplot script, since Maxima (and package draw) knows when it's running
   under windows.

When I look at src/maxima.bat it looks like the batch file does set a
bunch of variables based on the shell variables. Maybe someone who
knows the dos scripting language could look at this? Leo
