Windows 10: .jar file text always looking corrupted

Whenever I open a jar file any text inside of it just looks like its corrupted. As example, thescreenshot here is my most recent encounter. It's just a Minecaft tool but I have the same with any jar file and I have no idea why. My first guess is that it came from me changing my system font, but even after changing it back I didn't saw any difference. I tried to re-install Java but also didn't saw any fix of this problem. Some tools like jarfix.exe are useless as well, since the files still work perfectly, just the text is corrupted. Any button, text-box, etc still works.
If I try to type something, it is like I would literally use some Caesars Code encryption, it feels like the whole alphabet just shifted. If I type A, it gets displayed as C, B as D, C as E, etc, Z is \, the same logic applies to all numbers or special characters like @%$# etc. Sometimes there are just random spaces. I tried to search in the internet for people with similar problems, but didn't found any. I also tried to restart my pc, turn off any Antivirus, re-download both some jar files and Java but nothing. I have absolutely no idea what causes this problem, and I just hope that there is a way to fix this without having to re-install windows.

I am currently running:

-Java 8 Update 271 64 bit

-Windows 10 Pro Version 20H2 64 bit

jar files

Fixing .jar file opening on Windows requires two steps:

• Open the Control Panel, and chose "Default Programs - Associate a File type or protocol with a program". Find .jar extension (Executable JAR file) there, and pick Java as default program to open this extension. It will probably be listed as "Java Platform(SE)".
  A faster alternative perhaps is straightforward right-click on a .jar file, and then change associated program by clicking on the "Change..." button.
• Now open the regedit, and open the HKEY_CLASSES_ROOT\jarfile\shell\open\command key. Luckilly for us, we may specify parameters there for the (Default) value. This is normally: C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

I Hope this Answers your Question!

 

Corrupted file RAR

If the archive has been created using WinRAR, why don't you try WinRAR itself? It has a built-in repair feature for repairing corrupted archive (ZIP as well as RAR). Follow the steps given below:

• Open WinRAR application in your system.
• Now click on File tab > Open or simply press Ctrl+O.
• A small window "Find Archive" will pop up. Locate the corrupt RAR archive from your system directory and select it.
• Now click Open button.
• Click Tools tab > Repair archive or simply press Alt+R.
• Again a small window "Repairing File name.rar" will pop up.
• Now click Browse to select a location to save the repaired archive.
• Check the box "Treat the corrupt archive as RAR" and click OK.
• WinRAR will start repairing of corrupt RAR archive. Once it gets completed click Close.

I hope the above steps will help you repair the corrupted RAR archive.

Thanks.

 

Java .jar file is not downloaded as a java file.

Have you tried the second solution?

"Open the Settings app. Navigate to the System > Default apps.

Scroll all the way down and select Choose default apps by file type.

Locate the .jar file type and choose a default application.

This method offers limited options and you can only choose applications recognized by Windows 10. Fortunately, there’s another method that you can try. To change file associations, do the following:

Press Windows Key + X to open Win + X menu and choose Control Panel from the list.

When Control Panel opens, select Default Programs.

Click on Associate a file type or protocol with a program.

Locate the .jar file on the list and double-click it.

A list of suggested applications will appear. Click on More apps.

Scroll all the way down and choose Look for another app on this PC.

Locate the javaw.exe file. By default, the application should be located in Program Files folder. Select the application and choose it as a default for .jar files.

Optional: Some users recommend changing the parameters of javaw.exe. To do that, simply locate the file and create its shortcut. Right-click it and navigate to the Properties. Now, locate the Target file and add -jar “%1” % . Be sure to select this newly created
shortcut in Step 7.

You can also change file association by right clicking the jar file and choosing Open With > Choose another app. After doing that, follow the steps 5 to 8 from the above"
