    Default Problems Display Unicode Directly from Keyboard

    Hi dear Java Community,

    I have developed many Java projects, but am working on my first Unicode project. I have searched the appropriate forum threads (such as, Trying to display Unicode characters, etc) and the internet, etc, but there does not appear to be much info on this subject.

    For test purposes, I have just a basic setup:

    1. My Java file is to UTF-8 encoding.

    2. A simple Java code as follows:

    public class TestUnicode {

    public static void main (String args[]) {
    System.out.println ("Trying to display unicode character: \u011f. Thanks");
    }

    }

    From command line using Java 1.6:

    javac -encoding UTF-8 TestUnicode.java

    (compiles fine, but upon running it...)

    java -Dfile.encoding=UFT8 TestUnicode

    I get the following:

    Trying to display unicode character: ─.

    (which is the incorrect character, however if, I run it without the encoding, then I get the following...)

    Trying to display unicode character: ?.

    (JVM getting confused even further or is it me?)

    Any ideas?


    Regards,
    Jamie

    Hi,

    I have solved the problem:

    The Command Prompt (MSDOS Windows) needed to be set to UFT-8 encoding, which was accomplished by invoking..

    chcp 65001

    ..at the prompt. This sets the environment to UFT-8. Then I ran the Java program as UTF-8 as follows...

    java -Dfile.encoding=UFT8 TestUnicode

    Problem solved.

    Regards,
    Jamie

    Hi,

    Sure I can, but please do note that this is to run Java via a Command Prompt using MSDOS Windows:

    1. Each time you open up a DOS Window (by clicking on Start logo, then All Programs, then Accessories, then Command Prompt)

    2. Set the Window environment to Unicode by typing at the prompt:

    chcp 65001 (and then press the Enter/Return button)

    3. If you have written a Java program and lets say it's called TestUnicode.java, then type the following to compile the code:

    javac TestUnicode.java (and then press the Enter/Return)

    4. Then finally, to run the program called TestUnicode that has Unicode characters that are stored in Strings and Collections, then type the following:

    java -Dfile.encoding=UFT8 TestUnicode

    5. Assuming that your program displays the Unicode characters, then you will see at the DOS Window your Unicode characters being displayed correctly (hopefully).

    I hope the above helps.

    Take care...

    Kind regards,
    Jamie
