JShell encoding in DOS/Windows

I have the equivalent problem with German settings.

It works fine under Linux (xUbuntu 18.04) but on Windows10, there are problems with non-US-characters.

If I type in the REPL (aka JShell)

> println ("ÄÖÜäöü߀")

I can see it exactly as written and expected/hoped for, but the feedback, when hitting ENTER, is funky characters, question marks upside down and the like - I'm now not on the machine with this error, else I would post the exact output.

If I write the command in notepad++ and save it to a file, sample.java, and load it into rhe REPL with

> /open sample.java

I have the same issues, but I can change the encoding in notepad++ to OEM850, CP1252 which used to be used with Win95/98 afaik, and with OEM(?)850 I get close: Only the small ü and the Euro-Symbol fail. But that seems to be an ancient approach - shouldn't UTF-8 work for all Western-European Countries, the US, Australia, most African Countries and South-Amerika, except from newline-issues with Windows, Mac and Linux?

However, notepad++ add a BOM to the file and the BOM creates new problems. Sadly I don't remember which exactly.

I guess jkostaras-JavaNet is referring to cmd.exe, when talking about the "DOS-Window". It's not a DOS-Window.

I tested it with cmd.exe and Powershell and just starting JShell from the Windowsmenu - that didn't make a difference.

I looked for a promising switch to change the encoding but didn't find anything. Now, on my Linuxmachine, where I don't have these issues, I suspect I might should try the -J -switch on jshell-startup, but I'm unsure what I shall try -

* file.encoding = UTF-8

* sun.jnu.encoding = UTF-8

* user.language = de

* user.country = DE

* default display locale = Deutsch (Deutschland)

and how, or something else?

1) set system enviroment variable  JAVA_TOOL_OPTIONS=-Dfile.encoding=utf8

2)execute chcp 65001 before jshell  or add it to registry(see photo below)

3)files loaded in jshell (/open command) must be saved in utf8 encoding without BOM (you can use notepad++ for this)
