@StanFromIreland

@StanFromIreland This is likely due to how cpython expects char and file encodings and ends up trying to decode/encode chars that don't exist in Latin 1

TD;LR: Latin 1 can't encode characters such as U+4e00 which was mentioned in some error messages because there is no encoding for that unicode char in latin1! Latin 1 is 256 characters vs. Unicode ...

This log output only proves it:

UnicodeEncodeError: 'latin-1' codec can't encode character '\u2013' in position 166: ordinal not in range(256)

This should probably be documented in the devguide. I'd be happy do it.

@sharktide

@sharktide

I am well aware, and I have read the error messages.

The problem is that tests should be skipped if they are not supported by the platform (or updated to do so).

@StanFromIreland

@StanFromIreland This is also a valid solution

I'll start working on a PR.

@StanFromIreland

@StanFromIreland
Considering that this issue might arise multiple times in the same test script, do you think that we should completely skip the tests and just add a warning for users on latin 1 rather than cherry-pick every possible cause of these, which wouldn't really help anyway?

For test httpservers this might be okay, but for other ones like test_zipfile it might be extremely hard to pinpoint it. I'll work on a fix for that

Skipping tests is not always the best solution. First try to find the root cause of the error. It may be a bug in the test, and it may be a bug in the tested code.

From my understanding test_httpservers was a test error so I opened the PR.

Same for test_zipfile and test_asyncio. I made PRs for those 2

pythongh-133677: Fix tests when running in non-UTF-8 locale

There are more failing tests: test_fileio, test_sys, test_tarfile.

test_httpservers, test_sys and test_tarfile are bugs in the stdlib and require separate PRs. #133865 fixes the rests of tests.

@hauntsaninja

There are some fails specific to 3.14 see in test_venv, the pi symbol (π) is being decoded. This is because of the πthon link in the bin directory. What should we do with this one?

cc @hauntsaninja who added it IIRC

We could catch the exception or filter out the suffix if we can't encode it. We can also just remove the easter egg on main. PEP 686 will make this all moot anyway!

The Easter egg does not exist on main; was this a regression?

Code still exists on main for now, but the easter egg is version gated since it's 3.14 (pi) specific

We can also just remove the easter egg on main.
