New submission from john_miller <johnson.b.ourne+pythonbugtrac...@gmail.com>:
I noticed some beeping when printing data to the console (cmd), so I narrowed down the problem to three specific Unicode-characters somehow producing beeps when printed to the Windows console (CMD). This also works in interactive mode. (I checked every single Unicode-character up to sys.maxunicode (except character-values between 0xD800 and 0xE000) by bisecting ever-more fine-grained until I narrowed it down to only those three characters producing unwanted beeps.) Isolated example of bug: for i in ['\u2022', '\u2024', '\u2219']: print(i) \u0007 beeps too, but this works as intended. Python version: 3.8.5 (tags/v3.8.5:580fbb0, Jul 20 2020, 15:43:08) [MSC v.1926 32 bit (Intel)] Windows version: Microsoft Windows 7 Professional (6.1.7601 Service Pack 1 Build 7601) CMD active code page: 850 (According to chcp-command.) sys.stdout.encoding: utf-8 Might be loosly related to PEP-528 (https://www.python.org/dev/peps/pep-0528/) Addendum: Piping the output like: 'python.exe script.py >> testfile.txt' produced an error. This might happen with more Unicode characters but I haven't checked.
