Replacing Unicode characters in a String

Question

I have a text as a String and in this text which is foreign language appears sometimes characters in Unicode format as ö or Ö
The question is, how can I convert this String so these Unicode characters would become readable characters.
Thank you for any lead...

Answer 1

:-) Interesting - twice in 10 minutes I'm recommending the use of Elliott Hughes' class. See http://elliotth.blogspot.com/2004/07/java-implementation-of-rubys-gsub.html .
You just have to write a regular expression to match the terms ( "&#(\\\d+)"), extract the number as a string (group(1)) then use the Integer.parseInt(the numeric string) and cast to a char.

This is an example I wrote a couple of years ago (and published on the old Sun site forums) that does pretty much exactly what you need
import e.util.Rewriter;
public class Sabre20090919
    public static void main(String[] args) throws Exception
        String title = "& #26412;& #26399;& #28136;& #21033;\n" +
                "& #22522;& #26412;& #27599;& #32929;& #30408;& #39192;\n" +
                "& #32380;& #32396;& #29151;& #26989;& #21934;& #20301;& #28136;& #21033;\n" +
                "& #26371;& #35336;& #21407;& #21063;& #35722;& #21205;& #32047;& #31309;& #24433;& #38911;& #25976;\n" +
                "& #26222;& #36890;& #32929;& #27599;& #32929;& #30408;& #39192;\n" +
                "& #31232;& #37323;& #27599;& #32929;& #30408;& #39192;\n";
        Rewriter rewriter = new Rewriter("&\\s*#(\\d+);")
            @Override
            public String replacement()
                return Character.toString((char) Integer.parseInt(group(1)));
        title = rewriter.rewrite(title);
        System.out.println(title);
        System.out.print("Unicode :\"");
        for (char ch : title.toCharArray())
            System.out.printf("\\u%04x", (int) ch);
        System.out.println("\"");
        byte[] asBytes = title.getBytes("big5");
        for (byte b : asBytes)
            System.out.printf("%02x ", (int) (b & 0xff));
        System.out.println();
}The rest is just a test harness.
