Subject: [PATCH] Fix test_detect_encoding() with chardet 6.0.0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The old version was tested with chardet verisons including 5.2.0, which
worked.

The test failed on OpenSUSE Tumbleweed with python313-chardet-6.0.0-1.1
