A problem with macros in DataLab v1.0.1?

[deuterium33]

Describe the bug
When I execute a macro, even the example "toto" macro, I get the error:
...\Lib\encodings\cp1252.py", line 19, in encode
return codecs.charmap_encode(input,self.errors,encoding_table)[0]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
UnicodeEncodeError: 'charmap' codec can't encode character '\u2192' in position 0: character maps to

To Reproduce
Steps to reproduce the behavior:

Installation information

DataLab v1.0.1 on a fresh conda environment with Python 3.11 and DataLab installed via "pip install datalab-platform[qt]"

I could fix it by adding

import sys
sys.stdout.reconfigure(encoding='utf-8')

at the begining of my macro.

Hi,
Thanks for the feedback.
Fix is on the way.
Meanwhile, you may prepend all your macros with your fix: that's a good workaround.

Thank you! I also thought it was a good idea to have my conda Python DataLab environment have 'utf8' as default encoding, so I did:
conda env config vars set PYTHONIOENCODING=utf-8 PYTHONUTF8=1
which also fixed the issue. Strangely, it did not default to that for a Python 3.11 environment. Anyway, that's a good fix to have in case.
