Re: problem with java displaying unicode, under ms-windows

....
I copied some text from www.mainichi.co.jp into Libre Office. I saved
the text as UTF-8. I used the program below to display it. It isn't
quite correct though, I get a dot before the text that wasn't on the web
page. Other than that it works fine.
