I have a worksheet with non-ascii characters in the source code (utf-8 comments). If I have 'sage' selected in the combo-box on top of the worksheet then "Save worksheet to a file" works well. But if I change this to 'python' than calling "Save worksheet to a file" leads to a UnicodeDecodeError:

'ascii' codec can't decode byte 0xd0 in position 6: ordinal not in range(128)

I've opened https://github.com/sagemath/sagenb/is... for this, though note that the sagenb is now in extreme maintenance mode. You may wish to try to convert to a Jupyter worksheet where perhaps this naming issues is resolved.

Learned about Jupyter for real last evening, bot that problem and some other problems are not present in Jupyter (and Jupiter seems prettier, not sure about the Jupyter's markdown vs Sage's rich text boxes and Jupyter's versioning vs Sage's versioning thought). I think because of Jupyter this question is outdated, and the related github issues may also be closed in order not to draw developers attention and save time. Still thanks :)
