this does probably depend  on the how rrdtool for windows was
compiled ... since windows does not generally contain support for the
strftime function (which is used to do all the time formatting),
rrdtool contains a small public domain version of that function
wich can be compiled in when the OS does not supply an
implementation ... the simple version included with rrdtool only
support english weekday and month names (they are compiled in hard
coded) ...

if your rrdtool is compiled with some posixish layer on windows,
the LANG setitngs should work, but otherwhise there is no helping
it short of modifying the source and recompiling ... (or switching
to some unix system with proper strftime implementation).

I?ve not tried this yet, but I think you need to use the ?font option to specify a TrueType font that has the required characters first.  EG:  --font ?DEFAULT:0:Courier New? will change the default font name for all text to ?Courier New?.  See the documentation here http://oss.oetiker.ch/rrdtool/doc/rrdgraph.en.html
