Is it possible to add the Cyrillic text to the plot in Sage Notebook?

Currently I am trying to do somethink of this kind:

total_plot = plot(sin(x),-10,10)
total_plot += text("????????", (5,0.5))
total_plot.show(figsize=(4,3))

Sage gives the error message:

ValueError: matplotlib display text must have all code points < 128
or use Unicode strings

If I add the 'u' symbol before the string

total_plot += text(u"????????", (5,0.5))

I can only see the empty rectangles instead of the letters.

P.S. I saw this question, however, I am more interested in not using Matplotlib directly if possible.

Hello.
Please see http://wikisage.ru --> Grafika sredsvami mathplotlib --> Razonoe --> Rusificatsia Mathplotlib. This page is on Russian but has fully documentation for your quesiton.

Shortly you need to do:

import matplotlib as mpl
mpl.rcParams['font.family'] = 'fantasy'
mpl.rcParams['font.fantasy'] = 'Arial' # for Windows
mpl.rcParams['font.fantasy'] = 'Ubuntu' # for Ubuntu
mpl.rcParams['font.fantasy'] = 'Arial, Ubuntu' # for Windows and Ubuntu
plt.title(u'Your text in Russian')
plt.show()

P.S. Wikisage.ru is my project. I collect information on Russian how to work in Sage and regulate my own knowledge as well.

Thanks! It workes just fine. And since it does, I suggest you editing this answer by adding the minimum recipe for Sage Notebook: import matplotlib as mpl; mpl.rcParams['font.family'] = 'fantasy'; mpl.rcParams['font.fantasy'] = 'Arial'; text(u"?????????",(1,1), figsize=(2,2))

By the way, it is not necessary to use matplotlib directly, as you shown above (like 'plt.title...'). These settings are also applied to the sage native plotting functions such as 'plot', 'text' etc.
