Outlook is a popular email client used by many on Windows 11. Sometimes, users face issues with Outlook not supporting Unicode characters properly. This can cause problems with displaying foreign languages or special symbols in emails.
Unicode support is essential for reading and sending emails with diverse characters. When Outlook does not handle Unicode correctly, emails may look broken or show strange symbols.
This guide will help you fix the Unicode support issue in Outlook on Windows 11. The steps are simple and explained clearly, so even beginners can follow along.
By the end of this article, you will understand how to troubleshoot and solve this problem effectively.
Quick Note: Prerequisites and Checks
Before starting, make sure of the following:
- You are using a supported version of Microsoft Outlook on Windows 11. Unicode support is better in newer versions.
- Your Windows 11 system is updated with the latest patches and updates.
- You have a backup of your important emails and Outlook data, just in case.
- Check if the problem happens with all emails or only specific senders.
Step 1: Check the Email Encoding Settings in Outlook
Outlook uses encoding settings to display text correctly. If the encoding is wrong, Unicode characters may not show properly.
- Open Outlook and go to the File menu.
- Select Options at the bottom.
- In the Outlook Options window, click Advanced from the left panel.
- Scroll down to the International options section.
- Make sure the option “Automatically select encoding for outgoing messages” is checked.
- Also, ensure that “Send messages in Unicode format (UTF-8)” is enabled if available.
- Click OK to save changes.
This step ensures Outlook tries to use Unicode (UTF-8), which supports most characters worldwide.
Step 2: Change the Reading Encoding for Incoming Emails
Sometimes, incoming emails are displayed incorrectly because Outlook uses the wrong reading encoding.
- Open the problematic email.
- Click on the Message tab on the ribbon.
- Find the Actions group (you may need to click on the three dots … to see more options).
- Click Other Actions > Encoding.
- From the list, try selecting Unicode (UTF-8) or other Unicode options.
- Check if the email text now displays correctly.
This manual adjustment fixes the display for emails that use a different encoding than Outlook expects.
Step 3: Verify the Windows System Locale Settings
Windows system locale controls how non-Unicode programs display characters. If it is set incorrectly, Outlook may have trouble displaying Unicode.
- Press Windows key + S, type Region settings, and open it.
- Scroll down and click Administrative language settings under the Related settings section.
- In the new window, click Change system locale…
- Ensure it is set to your preferred language that supports Unicode (usually your native language or English).
- If you make any changes, click OK and restart your computer.
Correct system locale helps Windows and applications like Outlook handle Unicode properly.
Step 4: Update Outlook and Windows
Outdated software can cause compatibility issues. Make sure both Outlook and Windows 11 are fully updated.
- Open Outlook.
- Go to File > Office Account.
- Click Update Options > Update Now to check for Outlook updates.
- For Windows updates, press Windows key + I to open Settings.
- Click Windows Update and then Check for updates.
- Install any pending updates and restart your PC.
Keeping software updated ensures Unicode support and bug fixes are applied.
Step 5: Repair Outlook Installation
If problems persist, repairing Outlook might fix corrupted files affecting Unicode handling.
- Press Windows key + S, type Apps & features, and open it.
- Find Microsoft Office or Outlook in the list.
- Select it and click Modify.
- Choose Quick Repair first, then click Repair.
- If the issue remains, try Online Repair which takes longer but is more thorough.
- Restart your computer after repair.
Alternative Method: Use Outlook Web or Another Email Client
If you urgently need to access emails with Unicode characters correctly, try the following alternatives:
- Use Outlook Web Access (OWA) via your browser, which usually handles Unicode well.
- Try another email client like Mozilla Thunderbird or Windows Mail temporarily.
These options help you continue working while troubleshooting Outlook desktop issues.
