Maybe incompatible with zh_cn locale

My test enviroment :

• IJava 1.1.2
• jupyter 4.4.0
• Windows 10 x64

• windows language is CHS

  There are right error hint in Chinese in jshell.

but it throw exception in jupyter

I just gave this a try on a linux and it seems to be working fine, the error messages that were propagated from jshell displayed properly.

The only thing that might be different with windows is the default encoding. Could you try the following steps to see if that fixes the issue, and if it does I will try to get that default into the software so it doesn't require external configuration.

• search the output of jupyter kernelspec list for the location of the java kernel
• in that folder edit the kernel.json

  
  {
  "argv": [
      "java",

• "-Dfile.encoding=utf8", "-jar", "/path/to/ijava-1.1.2.jar", "{connection_file}" ], ... }

[tqjason]

It's working.

Thanks.

I would also be very happy, if this line was in the default kernel.json. I used the IJava-Kernel for a bridging course in programming in Germany. My students would regularly add german umlauts to variable names and then wonder why their program does not compile and does not even produce an error message.

Hello @tqjason and @CSchoel, I believe this issue is fixed upstream now. Would either of you mind testing the kernel from master here and confirm?

The -Dfile.encoding=utf8 should no longer be necessary. I was able to execute

System.out.println("\u6F22漢字");
String 漢 = "test漢";
漢

I am not sure of what the characters are, just copied from wikipedia :) It used to cause the same issue originally referenced but that seems to be fixed now.

Thanks in advance!

Hey, I just compiled and tested the current version of the kernel. The following example code ran without errors:

int xö߀ = 7 + 4;
System.out.println("x = "+xö߀);

I also tested your Chinese example and it worked fine. I think the issue is resolved. Thank you very much. :smiley:

Fantastic, thanks @CSchoel!
