566. Briefly: Annoying warnings when plotting using gnuplot and octave on wheezy March 2014.

Note: I'm not going to give a proper fix for this, but rather a work-around -- and one which isn't very good at that.

When using gnuplot or plotting in octave on wheezy I keep getting the following warnings.

My 'solution' was a bit radical -- I had already set up a system with apt-pinning (http://verahill.blogspot.com.au/2014/03/562-pulling-in-glibc-214-from-testing.html) so I figured that pulling in the fonts from testing couldn't hurt, assuming there were no dependencies to worry about.

So I did:

sudo apt-get install -t testing fonts-arphic-uming

and this worked fine.

The old 41-arphic-uming.conf:

It just remained to pull in the rest of the offending fonts:

sudo apt-get install -t testing fonts-arphic-ukai fonts-droid fonts-baekmuk
