UnicodeEncodeError when uploading non-ascii filenames

[Chrescht]

When uploading a file with non-ascii characters, I get the following error:

UnicodeEncodeError at /url_removed/

'ascii' codec can't encode character '\xe9' in position 56: ordinal not in range(128)

Request Method: 	POST
Request URL: 	url_removed
Django Version: 	3.2
Exception Type: 	UnicodeEncodeError
Exception Value: 	

'ascii' codec can't encode character '\xe9' in position 56: ordinal not in range(128)

These are the steps to reproduce the issue:

1. PrivateFleField in my model: id_file = PrivateFileField(upload_to='id/', max_file_size=size_3mb, null=True, blank=True) and add it to a form.
2. upload a PDF file with filename containing the character é as an example: "carte d'identité.pdf"
3. Django throws an UnicodeEncodeError

Where can I set the encoding codec?

Python 3.8.5 and Django 3.2

Does nobody have an idea how to change the default ascii encoding?

The Python default encoding is utf-8:
python -c 'import sys; print(sys.getdefaultencoding())'

At least several of the main developers should know exactly how to deal with this.

The issue was with the apache webserver after all.
Adding the following two lines to the file etc/apache2/envvars did the trick:

export LANG='en_US.UTF-8'
export LC_ALL='en_US.UTF-8'

Don't forget to restart apache. A reload is not sufficient.

Displaying the file does not work yet though..the non-ascii file is not found.
