Report the Bug and Use OneNote for Web as a Workaround

Since this is a known bug in OneNote for Microsoft 365, reporting it officially helps Microsoft investigate and issue a fix. In the meantime, use the web version where fonts render correctly.

Independent advisors and community volunteers have identified this as a specific limitation within the desktop app's rendering engine. Because users cannot directly patch Microsoft engineering bugs, submitting detailed feedback is the most effective way to push for an update.

1
Open OneNote Desktop

Launch your OneNote desktop application and navigate to the 'File' tab located in the top-left corner of the window.

2
Navigate to Feedback

Click on 'Feedback' from the left-hand menu, then select the 'Report a Problem' option.

3
Detail the Issue

Describe the display problem. Be sure to include the specific Tamil font name, the affected text, your current Office version, and screenshots showing how it looks in OneNote compared to Word.

4
Use OneNote for Web

As a temporary workaround, open your web browser, log into your Microsoft 365 account, and use OneNote for the web to view and edit your Tamil text without display issues.

Frequently Asked Questions

Why do Tamil fonts work in Word but not in OneNote desktop?

OneNote desktop relies on a different text rendering engine compared to Word, Excel, or PowerPoint. Currently, this specific engine has a known bug in Microsoft 365 that fails to render certain Tamil Unicode scripts properly.

Will reinstalling the OneNote application fix the Tamil font issue?

No, reinstalling the application will not resolve the issue as it is an inherent bug in the current release of OneNote for Microsoft 365. You must wait for an official patch from Microsoft.

Are there any alternative ways to view my Tamil notes locally?

You can export your OneNote pages to Word or PDF formats, which handle Unicode fonts correctly, or you can temporarily use OneNote for the web where the font display works as intended.
