### Cyrillic text on the plot

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.
