 |             - if you want MBCS set tinyfd_winUtf8 to 0  |
 |             - functions like fopen expect MBCS          |

- Here is the Hello World:
    if a console is missing, it will use graphic dialogs
    if a graphical display is absent, it will use console dialogs
		(on windows the input box may take some time to open the first time)
