Which terminals are used and what's the output of `locale` and `cat --version` in both cases?

Linux:

   $ echo "$TERM"
   xterm-256color

   $ locale
   LANG=en_US.UTF-8
   LC_CTYPE="en_US.UTF-8"
   LC_NUMERIC="en_US.UTF-8"
   LC_TIME="en_US.UTF-8"
   LC_COLLATE=C
   LC_MONETARY="en_US.UTF-8"
   LC_MESSAGES="en_US.UTF-8"
   LC_PAPER="en_US.UTF-8"
   LC_NAME="en_US.UTF-8"
   LC_ADDRESS="en_US.UTF-8"
   LC_TELEPHONE="en_US.UTF-8"
   LC_MEASUREMENT="en_US.UTF-8"
   LC_IDENTIFICATION="en_US.UTF-8"
   LC_ALL=

   $ cat --version
   cat (GNU coreutils) 8.29

Cygwin:

   $ echo "$TERM"
   cygwin

   $ locale
   LANG=en_US.UTF-8
   LC_CTYPE="en_US.UTF-8"
   LC_NUMERIC="en_US.UTF-8"
   LC_TIME="en_US.UTF-8"
   LC_COLLATE="C"
   LC_MONETARY="en_US.UTF-8"
   LC_MESSAGES="en_US.UTF-8"
   LC_ALL=

   $ cat --version
   cat (GNU coreutils) 8.26

Note that in addition to Linux, Windows PowerShell also gives correct output:

   $ pwsh -c '[system.text.encoding]::UTF8.getString(0xEB)'
   �

compare again with Cygwin:

   $ printf '\xEB'
   ▒
