问题
The problem seems trivial, but could not find a solution so far.
C:\Users\User>"C:\Program Files\Java\jdk1.8.0_112\bin\java" -jar "D:\Valya\Учёба\ТРПК\наумов_трпк_лаб2\build\libs\naumov_trpk_lab2-runnable.jar"
Error: Unable to access jarfile D:\Valya\?????\????\??????_????_???2\build\libs\naumov_trpk_lab2-runnable.jar
The issue appears only when I try to access a jar that is sitting in a dir with non-ASCII name. I am 100% sure I could run jars with such a path when I was on Windows 7, but since I moved to Win 10, no luck. Quoting the path does not help, -Dfile.encoding=UTF8 also.
BTW, if I run app from Intellij IDEA clicking on the main method, I get the following error.

My java version is
java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)
Feel free to ask for any additional info, cause I have just no clue.
UPD The original version of Windows, on which I had the issue is Win 10 LTSB installed with English (US) locale. But with the Russian locale installed from scratch on VM the problem is gone. And output is:
C:\Users\User\Documents>java -jar наумов_тпрк_лаб2.jar
Error: Invalid or corrupt jarfile эрєьют_ЄяЁъ_ырс2.jar
Yes, corrupt because it's plaintext, but path is found, no original error. Don't let the letters fool you, that was not a chcp problem: although original codepage is 866, any other let java find path to the file.
回答1:
Firstly, -Dfile.encoding=UTF8 has nothing to do with filenames, but has something with filecontents.
And the sweet part.
- Open start menu, type to find "Region & language settings".
Go to Related settings.
Then click on Change location...
And set the proper country
So, it finally works, but I hope someone provides details on this.
