Re: [Matplotlib-users] default mathtext font
Thank you Michael,
I tried switching the matplotlib font to Dejavu Sans but it also does not
seem to recognize the lunate epsilon ϵ.
When I wrote title(u'ϵ-Fe'), it printed ε-Fe instead.
I tried several other fonts but the problem did not disappear.
It seems that the bes choice after all is to write r'$\rm{\epsilon-Fe}$'.
Thanks again

It looks like the default Vera Sans font that matplotlib uses doesn't
actually have the lunate epsilon character. If you have it installed, you
could have matplotlib use the DejaVu Sans font instead (which is essentially
Vera Sans with a larger set of characters).
In your matplotlibrc, set font.sans to DejaVu Sans

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 ?

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. That's done
with a little magic comment at the top of the file. The popular
Unixy editors (emacs, vim etc.) also understand this comment and
will save the file correctly. Possibly other editors do as well.
For more gory details that you probably need, see this:
http://www.amk.ca/python/howto/unicode
particularly the section Unicode Literals in Python Source Code.

I have an editor that supports unicode.
But, can you please explain better how do I make the coding
directive at the top of my source files ?
Where do I write the command:
# -*- coding: utf-8 -*-
Is it inside the python script ?
Sorry for the ignorance.
