This probably has something to do with an unsupported character set.
Are you sure month names are displayed correctly?

Try a couple of things:

1: change the environment before RRDtool graph is run.
   export LANG

2: set an X-axis grid and label yourself, using the "-x" option
   --x-grid HOUR:8:DAY:1:DAY:1:0:%A
   (copied from TFM)
   perhaps play a bit with the various elements of this setting
