Java (including Swing) only uses one charset: Unicode. If you don't get
your characters displayed, then usually one of the following has happened:

        - You didn't use the appropriate charset conversion from an external
charset to Java's internal unicode. Your Java Strings and chars are
trashed due to the missing/wrong conversion. You will not only have
display problems, but other character and string related methods can
fail in mysterious ways (e.g. sorting).

        - You are using a font which doesn't have the necessary glyphs to
display the particular characters. Change to a font with the necessary
glyphs.

More unlikely reasons are

        - A trashed Java installation where e.g. the font.properties file is
trashed

        - A trashed OS, e.g. trashed OS font data

BTW: "extended characters" is a meaningless term.
