I wonder if I'm encountering the same bug (or something related). I had previously been using the .csv feature to run queries and then fetch results for the pandas read_csv() function, but it seems to have stopped working recently.

Here's the incomplete sketch of a test - to go at the bottom of test_cli.py.

python @pytest.mark.parametrize( "filename", ["test-database (1).sqlite", "database (1).sqlite"] ) def test_weird_database_names(ensure_eventloop, tmpdir, filename): # https://github.com/simonw/datasette/issues/1181 runner = CliRunner() db_path = str(tmpdir / filename) sqlite3.connect(db_path).execute("vacuum") result1 = runner.invoke(cli, [db_path, "--get", "/"]) assert result1.exit_code == 0, result1.output homepage_html = result1.output assert False

I'm going to add a unit test that tries a variety of weird database names.

Yes, that logic is definitely at fault. It looks like it applies urllib.parse.unquote_plus() AFTER it's tried to do the - hash splitting thing, which is why it's failing here:
