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

I get the non-ASCII Characters in the graph - by changing the character set of the editor which is used to create the batch files for the rrdgraph command from ANSI to CP850.
But unfortunately I am still not able to chage the language settings for the axis labels. I tried different environment variables (LANGUAGE, LANG, LOCALE) set to different values (DE, de, DE_de, de_DE, de_de) without success. The axis lables are always in english.
Anyone any idea?

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

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 GPRINT, TITLE, COMMENT etc.).
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, Sun”.
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!
