(Sorry for the delay -- just back from vacation) It looks like the default Vera Sans font that matplotlib uses doesn't actually have the lunate epsilon character.

In your matplotlibrc, set font.sans to DejaVu Sans Cheers, Mike Eli Brosh wrote: > Thanks, > This unicode thing works like magic. > The only thing I am still unable to do is to insert the symbol > \epsilon (as distinct from \varepsilon). > For some reason, the varepsilon ε is printed fine, but a blank square > is printed instead of the lunate epsilon ϵ. > That is u' ε ' works, while u' ϵ' does not. > > Any idea why this is happening ? > > Eli > > > 2008/7/22 Michael Droettboom <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>>: > > Yes, you would put it at the top of your .py file. > > In order to use Unicode in Python source code, you have to tell > the Python interpreter what encoding the file is in.
