Summary: plot doesn't work with special characters in Username

Initial Comment:

(%i3) wxplot2d([%o2], [x,-5,5])

$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.

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.

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.
