open "Western Europe Windows 1252 Win Latin1" files

How can I open “WesternEurope Windows 1252 WinLatin” files that were created on Windows? They open in Ubuntu Libre Office, But the curly quotes and certain other characters display as “?” in a box.

no info on lo-version, os-version nor filetype. Do you honestly expect an answer?

In which format are those “WesternEurope Windows 1252 WinLatin” files? Are they plain text files or .doc files created with some (which?) version of MS Word? Can you attach an example?
