Several tests fail when system encoding is `latin-1`

This *will* only affect < 3.15 when PEP 686 is implemented, they pass: https://buildbot.python.org/?#/builders/1677/builds/2

# Bug report

### Bug description:

See buildbot [run](https://buildbot.python.org/?#/builders/1678/builds/7). (Note: some tests are failing due to the timezone, that is tracked in a separate issue)
