Display Unicode Code from a String in Java?

rusty_turkey · 08-09-2006, 07:49 PM

Hi,

I'm trying to make a simple program that will display the corresponding unicode for a string of text.
eg.

String text = "some text";

System.out.println(convertToUnicode(text));

The program should display the unicode that represents the given string, such as:
\u2340\u2432\u2830...etc

Is there any way to do this without manually programming like this:
case 'a': return "\u2345"; // or whatever the code for 'a' is

I am not a java expert, but looking at the latest API, why not use something like Character.codePointAt() function. The result should probably be displayed in hex (for example with printf("\\u%04x\n", blah)).

I'm not quite certain what you have managed to achieve so far (and my Java is very rusty) but you should be able to take each character and using type conversion store it as a number. But maybe that's not your problem?

Code:

    String test = "ABCD";
    for ( int i = 0; i < test.length(); ++i )
    {
        char c = test.charAt( i );
        int j = (int) c;
        System.out.println(j);
    }

While I think this should also work fine (except maybe for characters outside of the BMP: IIRC, in Java, ints are 4 bytes and chars are 2 bytes), I don't think that's the "Java Way". Casting is discouraged in java in preference to using classes' methods.
