[rrd-users] Special language dependent characters in rrdtool runnin on Windows

The axis labels come from the strftime library, which picks the abbreviation
according to the Language settings.  Set the environment LANG=de (I think)
to make it pick German.  However, under Windows, it should be picking this
up from the internationalisation settings picked in the Windows OS?


To get non-ASCII characters inside the graph is a bit harder, though I
believe it is possible under RRDTool 1.3 and later.  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

on Windows




If running rrdtool (1.4.5) in Windows environment, I am not able to enter
special German characters (like äöüß etc.) anywhere inside a graph (like in


In addition, I would like to configure German labels on the axis like
“Mon,Die, Mit,Don, Fre, Sam, Son” instead of “Mon, Tue, Wed, Thu, Fri, Sat,

The documentation says, these strings depend on the current locale – but how
can I set the current locale for rrdtool in a Windows environment?


I do not use Perl – just rrdtool.exe.


Any hint would be very much appreciated!
