Java, not printing Chinese Character in Visual Studios Code, but works in Python

When I do
System.out.println('说');
It just prints "?"
In the bottom right corner it says UTF-8 (so that is good).
I have no idea what I am doing wrong, any help much appreciated.
PS: When I make a python file and print it, it prints it properly. But not in java :(
I tried doing System.setProperty("file.encoding", "UTF-8"); but same result sadly. I tried running code in repl.it, and it works. But not in visual studios.
Note that windows Locale is set to support UTF-8. And I am using Consolas Font, which should support UTF-8.
I also tried uninstalling VS and installing it again - it didn't fix anything.
I am also using terminal for all output.

What is your machine language? Change the system language to Chinese, and modify the system locale to Chinese(you may need to restart the computer), then restart vscode and print out Chinese characters.
Another simple and effective way is to use the Code Runner extension. Install the extension and execute the script with Run Code, the OUTPUT panel will display the result.

No cyrillic symbols in a string in IntelliJ IDEA

i've started developing in IntelliJ in Java, created a new gradle project, added a few libraries but encountered a problem that a string is not being filled with cyrillic symbols - instead i get incorrect symbols (screenshot attached). How can i fix it? It has something to do with encodings - I tried a lot of suggestions on the web but nothing helped. Cheers!

Just change all encodings into UTF-8 (or other preferable encoding) and reload all java files into UTF-8.
You must know how to do first part (if you don't: File(top left corner of your window)>Settings>Editor>File Encodings).
The second part is also easy: just click on encoding in bottom right corner of the window and choose UTF-8 (or other preferable encoding).
Then you will have window like shown below. Choose "Reload" and enjoy. If you still have questions you are free to ask.

Cannot verify text which contains diacritics

I am using selenium webdriver with java and trying to verify some texts I find on a page.
The text contains diacritics like ţ ă etc.
The problem I encounter is when I run my test from the command line using maven; I need to do this because I will be integrating them into Jenkins.
So I have a simple assert in my test:
Assert.assertEquals("some text with ţ", driver.findElement(text).getText());
which fails and I don't know what is the right way to make this work.
I have read that the default encoding for strings in Java is UTF-16, so when the text is taken from the page with getText, the string is already encoded and I suppose that means that the characters are lost. On the other hand, I don't know if the comparing text itself "some text with ţ" is interpreted ok.
Has anyone had problems similar to this? And how have you solved them?
Thanks

Maven is even issuing a warning specific to your error:
WARNING: character encoding not set. Using the platform default encoding, i.e., the
build is platform-dependent!
or a similar message.
The solution is to:
make sure you save the Java source code files in UTF-8;
make sure you explicitly configure the encoding in pom.xml (a setting on the Compiler plugin).

Eclipse UTF-8-weird characters

I am writing a program in java with Eclipse IDE, and i want to write my comments in Greek. So i changed the encoding from Window->Preferences->General->Content Types->Text->Java Source File, to UTF-8. The comments in my code are ok but when i run my program some words contains weird characters e.g San Germ�n (San Germán). If i change the encoding to ISO-8859-1, all are ok when i run the program but the comments in my code are not(weird characters !). So, what is going wrong with it?
Edit: My program is in java swing and the weird characters with UTF-8 are Strings in cells of a JTable.
EDIT(2): Ok, i solve my problem i keep the UTF-8 encoding for java file but i change the encoding of the strings. String k = new String(myStringInByteArray,ISO-8859-1);

This is most likely due to the compiler not using the correct character encoding when reading your source. This is a very common source of error when moving between systems.
The typical way to solve it is to use plain ASCII (which is identical in both Windows 1252 and UTF-8) and the "\u1234" encoding scheme (unicode character 0x1234), but it is a bit cumbersome to handle as Eclipse (last time I looked) did not transparently support this.
The property file editor does, though, so a reasonable suggestion could be that you put all your strings in a property file, and load the strings as resources when needing to display them. This is also an excellent introduction to Locales which are needed when you want to have your application be able to speak more than one language.

hebrew appears as question marks in netbeans

I am using netbeans 6.1 on 2 computers.
on one of them the program:
public static void main(String argv[])
{
System.out.println("שלום");
}
prints normally, and the on the other question marks.
what can be the difference between the 2 environments?
edit:
on both computers
Control Panel \ Regional and Language Options \ Advanced
is set to hebrew
edit:
Thank you Michael Burr,
but the value of the encoding is already UTF-8.
Maybe this something with the JVM?
edit:
I have installed Eclipse and the problem occurs there as well.
I also tried reading the hebrew from a file with the same result.
edit:
System.getProperty("file.encoding");
returns "Cp1252"
I tried
System.setProperty("file.encoding","UTF-8")
but the question marks remains.
Thanks,
Ido

Make sure that NetBeans is set up with an encoding that supports Hebrew characters. From the NetBeans Wiki:
To change the language encoding for a project:
Right-click a project node in the Projects windows and choose Properties.
Under Sources, select an encoding value from the Encoding drop-down field.

You can't set the "file.encoding" property with System.setProperty(); it has to be set on the command line when the JVM is started with -Dfile.encoding=UTF-8. The value of this property is read during JVM initialization and cached. By the time your main method is invoked, the value has been cached and changes to the property are ignored.

Is Hebrew installed by default? Could be that a language pack isn't installed?
Control Panel > Regional and Language Options > Languages. Select the 'Install files for complex script and right-to-left languages (including Thai)' option. This will install support for Hebrew. You'll probably need an OS disc.

How exactly are you running the program? Where does it print its output? It could be as simple as netbeans or the console using different fonts, one of which does not include Hebrew characters.
To eliminate encoding problems during compilation, try replacing the Hebrew characters with their unicode escape sequences and see if the result is different.

I think I misunderstood your problem (I thought that the characters were not being displayed in the NetBeans editor properly). The exact steps to solve your problem might depend on the version of the OS you're running on. Win2K, WInXP, and Vista all have slightly different dialogs and wording unfortuantely.
Take a look at this help page for the JVM:
http://java.com/en/download/help/locale.xml
It sounds like you've already configured the system like it should be, but the devil is in the details - there are several different 'locale' settings on a system that might affect this (and for all I know the JVM might throw in one or two on its own).
http://www.siao2.com/2005/02/01/364707.aspx

Usually it's the default encoding on:
Control Panel \ Regional and Language Options \ Advanced
(Select Hebrew on the combo)
You'll have to restart after changing this setting.

What helped me is this (on Win7):

No one answer from above doesn't work.
I spent about an hour, but had figured out, that the problem is located not in the String encoding, but in default encoding, which is used by IDE from the start-up.
So, to get Hebrew, Arabic, Russian etc symbols in Netbeans console output you need to modify netbeans.conf.
Search for the key netbeans_default_options and add -J-Dfile.encoding=UTF-8 into the quotes.
