@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

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).

[sharktide]

@StanFromIreland This is also a valid solution

I'll start working on a PR.

[sharktide]

@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

[serhiy-storchaka]

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.

[StanFromIreland]

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

[sharktide]

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