Problem / Steps to reproduce

Browsing directory with file names in Korean(non-Latin?) will leave some ghost chars in the console window as you scroll up/down.

At first, I found this issue in a VIM-embedded terminal. But when I tested in other environments (neovim, detached/embedded FZF windows, GUI/text), result was the same. Korean chars are left always. However I haven't tested it in native Linux terminal.

Also the issue can be easily reproduced with the attached text file.
type text.txt | fzf.exe
