Printing out unicode from Java code issue in windows console
cmd, encoding, java, unicode, utf-8
Solution
By default, the code-page using in the CMD of Windows is 437. You can test by run this command in the prompt:
C:\>chcp
Active code page: 437
And, this code-page prevent you from showing Unicode characters properly! You have to change code page to 65001 AND using -Dfile.encoding=UTF-8 for that purpose.
C:\>chcp 65001
Active code page: 65001
C:\>java -jar -Dfile.encoding=UTF-8 path/to/your/runnable/jar
Problem
I have got a problem with printing out a unicode symbol in the windows console. Here's the java code that prints out the unicode symbol value; ``` System.out.print("\u22A2 "); ``` The problem doesn't exist when I run the program in Eclipse with encoding settings as UTF-8, however when it comes to windows console the symbol gets replaced by a question mark. The following was done to try overcome this problem, with no success; Change the font of windows console to Lucida Console. Every time I run windows console I will change the encoding settings, i.e. with the use of `chcp 65001` An extra step I've tried a few times was running the java file with an argument, i.e. `java -Dfile.encoding=UTF-8 Filter` (where "Filter" is name of the class)
