the questions are in the wrong format, and not readable, could you please have a look? thanks @lhoestq

Comments:
If you print those questions, you get readable texts:
```python
>>> questions = [

I don't think we can change this

Hi @dorost1234.

In Python 3, strings are sequences of Unicode _code points_. Unicode is a specification that maps all characters (and emoji symbols) with its unique representation in terms of code points. That is what you see: Unicode code points (represented by a \u escaped sequence of 16-bit hex values).

Characters are usually represented (on screen and papers) with a graphical element called _glyph_. That is what you would like to see: glyphs. But Python does not care about glyphs: that is the job of the GUI or the terminal; glyphs are what you get with the `print` function (if your terminal is properly configured to display those glyphs).

You have more detailed information about Unicode in the Python documentation: https://docs.python.org/3/howto/unicode.html

thank you so much for the insightful comments.
