File encoding in txt files not properly recognized

[makedir]

I just installed Notepad3 on German Windows 11 24h2, also used German als language. But opening my txt files, Notepad3 does not properly recognize the encoding and shows "DOS-852" on the status bar. I have lots of wrongly encoded characters in my files looking like this:

Opening the same txt files in normal Notepad or other editors like Noepad++ works fine and it shows UTF-8, all characters are properly decoded there.
