There are several ways to get Unicode characters into your Java programs.
You are correct in that you can use \uxxxx to represent any Unicode
character. You put the escape sequence anywhere that you would put a
single character like "a" (so it goes inside the quotation marks).
If you can type the character itself, the NativeToAscii utility supplied
with the JDK will convert the characters to the escape sequence for you.
Note that in order to see the characters you will to have the proper fonts
(and, in the case of Windows, code pages) installed. Otherwise you'll see
"?" or an empty black square for your character. If you stick strictly to
Western European characters (as a proof of concept) you shouldn't have any
trouble, though.
You may wish to view the pages on Internationalization at the Javasoft
website. Try searching for "Internationalization" (you can also search for
"John O'Connor"-- he wrote several very clear introductory articles on the
topic and it reduces the noise in the search considerably.)
In the meantime, try using this line:
textstring="\u0109\u00e0\u00f1\u0020\u00fd\u00f5\u00fb\u0020\u0073\u00e8\u00e9\u0020\u00ef\u0074\u003f";
