Apache NetBeans 12.0 or 12.3 Window Tabs Label Text Language Issue - netbeans

Question

I am facing this weird language issue on Start Screen and as well as on other windows tab.
I have tried editing netbeans.conf files but no luck.
Please help me to resolve this issue.
UPDATE:
I have uninstalled version 12.0 and tried to install newer version 12.3 but issue is same as it was in 12.0

Answer 1

You could try the following options:
Use the latest JDK for Netbeans. The newest version for 1.8 is 281
How to point NetBeans to the new JDK see here.
Try to set the default language option for non-Unicode programs in windows as mentioned here.
Click Start > Control Panel.
Windows 10, Windows 8: Click Region
Windows 7: Click the Administrative tab.
(If there is no Advanced tab, then you are not logged in with
administrative privileges.)
Under the Language for non-Unicode programs section, select the desired language from the drop down menu.
Click OK.
Restart the computer to apply the change
If this doesn't help, try to change your java locale manually. You need to add something like this in the file netbeans.conf at the end of the variable netbeans_default_options:
-J-Duser.language=en -J-Duser.country=US -J-Duser.variant=UTF-8

You could try to change characters encoding for netbeans however my Netbeans version is differ from your but it should be the same approach fot thius. In my case i have netbeans config file (netbeans.conf) in a directory: C:\Program Files\NetBeans-11.1\netbeans\etc
I manually added -J-Dfile.encoding=UTF-8 to the default option ("netbeans_default_options"). Below I paste my netbeans_default_options value:
netbeans_default_options="-J-Djdk.lang.Process.allowAmbiguousCommands=true -J-XX:+UseStringDeduplication -J-Xss2m -J-Djdk.gtk.version=2.2 -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.java2d.dpiaware=true -J-Dsun.zip.disableMemoryMapping=true -J-Dplugin.manager.check.updates=false -J-Dnetbeans.extbrowser.manual_chrome_plugin_install=yes -J--add-opens=java.base/java.net=ALL-UNNAMED -J--add-opens=java.base/java.lang.ref=ALL-UNNAMED -J--add-opens=java.base/java.lang=ALL-UNNAMED -J--add-opens=java.base/java.security=ALL-UNNAMED -J--add-opens=java.base/java.util=ALL-UNNAMED -J--add-opens=java.desktop/javax.swing.plaf.basic=ALL-UNNAMED -J--add-opens=java.desktop/javax.swing.text=ALL-UNNAMED -J--add-opens=java.desktop/javax.swing=ALL-UNNAMED -J--add-opens=java.desktop/java.awt=ALL-UNNAMED -J--add-opens=java.desktop/java.awt.event=ALL-UNNAMED -J--add-opens=java.prefs/java.util.prefs=ALL-UNNAMED -J--add-opens=jdk.jshell/jdk.jshell=ALL-UNNAMED -J--add-modules=jdk.jshell -J--add-exports=java.desktop/sun.awt=ALL-UNNAMED -J--add-exports=java.desktop/java.awt.peer=ALL-UNNAMED -J--add-exports=java.desktop/com.sun.beans.editors=ALL-UNNAMED -J--add-exports=java.desktop/sun.swing=ALL-UNNAMED -J--add-exports=java.desktop/sun.awt.im=ALL-UNNAMED -J--add-exports=jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED -J--add-exports=java.management/sun.management=ALL-UNNAMED -J--add-exports=java.base/sun.reflect.annotation=ALL-UNNAMED -J--add-exports=jdk.javadoc/com.sun.tools.javadoc.main=ALL-UNNAMED -J-XX:+IgnoreUnrecognizedVMOptions -J-Dfile.encoding=UTF-8"
