For example, I run the top command and store it to a file in Linux, after that I open that file in Windows it contains some gibberish. Here is the file viewed in Notepad++:

File contents

The option to convert to UTF-8 in Notepad++ doesn't work.

How can I read that file in Windows? I tried using dos2unix but it doesn't work and gives the error:

dos2unix: Binary symbol 0x1B found at line 1

Edit: Trying the sed 's/\x1b\[[0-9;]*[a-zA-Z]//g' file.txt command gives the expected output but only in the terminal

    The right way is to tell tools like top not to print these characters in the first place. Some tools modify their behavior automatically if their stdout is not a terminal. It seems top does not do this. Use -b, e.g. top -b -n 1 >output; see man 1 top. In general, if some troublesome_program provides no option to turn ANSI escape sequences off, you can try passing TERM=dumb in the environment, e.g. TERM=dumb troublesome_program.

These are ANSI escape sequences/codes, so basically ESC character followed by some other characters that are used as sequences to display colors, etc.

To remove them, you can for example use ansi2txt CLI tool, e.g.:

top | ansi2txt > output.txt

Here are also more ways to remove them: Removing ANSI color codes from text stream
