$Maxima encountered a Lisp error: Error in APPLY [or a callee]: Cannot create the file C:/Dokumente und Einstellungen/blubb/maxout.gnuplot.Automatically continuing.To reenable the Lisp debugger set *debugger-hook* to nil.(%i4)

The Username is not correct. It must be b^l^u^b^b. It seems that special characters are ignored.

What are the special characters in question, I wonder? I'm pretty sure GCL does not know how to handle Unicode characters, although I would expect ISO-Latin-whatever would be OK ... Someone who has a foreign-language windows installation would be able to tell for sure.

It may be too late, but anyway, a work-around is to assign maxima_tempdir to some acceptable folder, say maxima_tempdir : "c:\temp". Then the plotting functions will put the Gnuplot output file there.

I wonder if this works as expected in SBCL or any other implementation, and not in GCL, or if it doesn't work in any implementation.
