This guide will help you turn on or off Unicode UTF-8 support in Windows 11. This feature helps your computer show languages from around the world correctly.

What is Display Language?

The display language is the language used in Windows menus, buttons, and messages. You can change it to a language you prefer.

Sometimes, when you change the display language, some programs might not show text properly because they don’t support Unicode. Turning on Unicode UTF-8 can fix this issue.

How to Turn On Unicode UTF-8 Using Windows Settings

Here’s a simple way to enable Unicode UTF-8 support using the Settings app in Windows 11:

1. Open Settings: Click on the Start menu and select Settings, or press Windows key + I on your keyboard.
2. In the Settings window, click on Time & language on the left side.
3. Click on Language & region on the right side.
4. Under Windows display language, look for the option Use Unicode UTF-8 for worldwide language support.
5. Turn the switch On to enable it or Off to disable it.

How to Enable Unicode UTF-8 Using the Registry Editor (Advanced)

If you like, you can also turn on Unicode UTF-8 support by editing the Windows Registry. But be careful — making mistakes here can cause problems on your computer. It’s best to back up your registry or create a restore point before you start.

Follow these steps:

1. Open the Registry Editor. You can find how to do this here: Open Registry Editor.
2. Go to this folder path:
   

   ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlNlsCodePage

3. Find the entries named ACP, MACCP, and OEMCP.
4. Double-click each one and change their values to 65001 to turn Unicode UTF-8 support on.

To disable Unicode UTF-8 support, change the values back to:

• ACP = 1252
• MACCP = 10000
• OEMCP = 437

After making these changes, restart your computer to apply them.
