pre-commit removes `# -*- coding: utf-8 -*-` pragma

Hello,

My CICD is running pre-commit run And it wants to remove the first line of percent file generate with jupytext --to py notebook.ipynb --set-formats "ipynb,py:percent"

The first line is: # -*- coding: utf-8 -*-

Related to the following hook: https://github.com/pre-commit/pre-commit-hooks/blob/master/pre_commit_hooks/fix_encoding_pragma.py

I would like to know what is the best way to handle this issue? Remove the line? Add some setting in pre-commit or jupytext?

Oh that’s interesting - maybe it’s time to remove this - I’ll give it a try and keep you posted.

I just look into the code and I saw: https://github.com/mwouts/jupytext/blob/cbfe2ff9e06610f2ddefd4d98646a551c25fba86/jupytext/header.py#L63-L67

I just tried now with an empty notebook, and it works, no first encoding line added. So It means have some non ascii characters in the notebook I was facing the issue with.

Sorry!
