 <p>The executable uxplay.exe can also be run without the MSYS2

+<p>There is a new modernized Windows Terminal application available from
+Microsoft that provides various terminals, and can be customized to also
+provide the MSYS2 terminals. See https://www.msys2.org/docs/terminals/

+UTF-8 encoding: To enter UTF-8 characters in the MSYS2 or other Windows
+terminals, use the numerical keypad with “Num Lock” on: while holding
+down the “Alt” key, type “+” on the keypad, followed by the UTF-8 hex
+code for the character (using the keypad for numbers), then release the
+“Alt” key. (The UTF-8 hex codes have 4 hex digits: for example, the
+“copyright” symbol has hex code 00a9.) This method must be activated in
+the Windows Registry: using regedit, find the Registry section
+’HKEY_Current_User/Control Panel/Input Method”, and add a new Key
+“EnableHexNumpad” with value “1”, then reboot the computer.</p>
