For STDOUT encoding detection errors, None is returned, which causes an error: "Argument 1 must be str, not none"

Description

Hello, the error occurs in the line “text = text.encode (encoding, ‘ignore’).decode(encoding)” of the “_format_text” function, because when determining the STDOUT encoding, there are cases of None type return (“Encoding [debugging]: cp1251 language, fs utf-8, out None, err None, prefix cp1251”). It would be good to define defaults in case of such errors.

Temporarily solved the problem using the following parameters: ‘no_color’: ‘True’, # Do not edit the color codes in the output ‘encoding’: ‘utf-8’, # BUG FIXED: [0 encode() argument 1 should be str, not No] (experimental)

[pukkandan]

yt-dlp normally detects the console’s supported encoding. The issue here is caused because python cannot detect it when being called from delphi (or other hooks?). So ascii is the “safe” fallback

[pukkandan]

I have fixed the error. But for maximum compat, yt-dlp falls back to ascii, not utf-8 in these cases. So if you know that you can handle utf-8, it is recommended to explicitly set the encoding
