This is caused by Munin not receiving valid UTF-8 data.

For this you have 2 possible solutions:

1) Patch munin-graph manually using:
http://munin-monitoring.org/svn/munin/branches/debian/lenny/trunk/debian/patches/380-munin-graph-utf8.patch

Note that the line numbers are a bit off if you are using another version.

2) Find the munin-node plugin that causes the problem(aka having some none utf-8 characters). Most likely it is the following line in the plugin hddtemp_smartctl:

print “graph_vlabel temp in °C\n”;

Change it to:

print “graph_vlabel temp in C\n”;

Restart the munin-node and you should not get more trouble, at least from that plugin.
