How to write to file Unicode characters

Question

I have PDF files that I need to copy some strings out of and put them in various fields in a Postgres database. The goal is a Java screen into the database, whiere I mark and copy the PDF text and then paste it into a field in a Swing window, and from there into the database.
I am unsuccessful at reading a PDF file, so I have opted to cut and paste the PDF file into an MS word file. This results in errors in certain unicode characters. I am trying to rectify them by a simple program, a start of which is below, by a replacement of the erroneous char by the proper unicode symbol. As, shown by the following, I cannot figure out how to write out a unicode character. Do I need to wrap (which I don't know much about yet)? Or do I have a file problem? (I have a Vista machine.) I don't think it should be impossible to write unicode into a file, as I am able to write into MS Word files phonological symbols, Russian, and Sanskrit. So, it must be in the java.
P.S.: I am reading Schildt's Java: A Beginner's Guide and am through chapter10, but remaining chapters are on threads, enumerations, autoboxing, static import, annotations; generics,; applets, events, and miscellaneous topics, and, finally Swing. Maybe its in the autoboxing?
Any help would be most appreciated.

          outputStream.println( "character9 " + uniChar);// yields character ?
          outputStream.println( "character10 " + '\u00FF');// yields character ÿ but fails on \u0100.
// only 0-255!!
          outputStream.println( "character11 " + cc);// yields ?
          outputStream.println( "character12 " + cb);// yields ?
          outputStream.println( "character13 ?");// yields ?
while ((c = inputStream.read()) != -1) {
     // outputStream.writeln(c);- error
} finally {
if (inputStream != null) {
inputStream.close();
if (outputStream != null) {
outputStream.close();
}
