How to Fix Tamil Text Appearing Jumbled in OneNote
Question details
The user needs to resolve an issue where Tamil text appears jumbled in OneNote, despite functioning perfectly in Microsoft Word.

- Product
- Microsoft OneNote
- Device & OS
- Windows 11
- Scenario
- Typing or pasting Tamil language text into a OneNote notebook.
- Observed behavior
- Tamil script renders incorrectly with jumbled characters and broken Unicode glyphs in the newer version of OneNote, unlike in older OS versions.
Ensure that your Windows 11 operating system is connected to the internet, as you may need to download additional system language resources.
Install the Tamil Language Pack and Select a Compatible Font
Ensure that Windows and Office recognize Tamil by installing the appropriate language pack and manually applying a Tamil-supported font in OneNote.
Sometimes OneNote fails to render complex scripts properly if the native language pack is missing or if the default font does not support the required Unicode glyphs.
Open Windows Settings, navigate to 'Time & language' > 'Language & region', and click 'Add a language'. Search for Tamil, select it, and install the language pack.
Open OneNote and go to 'File' > 'Options' > 'Language'. Under 'Office authoring languages and proofing', click 'Add a Language', select Tamil, and set it as preferred.
Highlight the jumbled text in your OneNote page. Go to the 'Home' tab and change the font to a known Tamil-compatible font such as 'Nirmala UI' or 'Latha'.

Update Microsoft Office and Windows 11
Software bugs related to Unicode glyph-rendering are often patched in regular Windows and Microsoft Office updates.

Frequently Asked Questions
Why does Tamil text work in Word but appear jumbled in OneNote?
Word and OneNote sometimes use different text rendering engines. A Unicode glyph-rendering issue may exist specifically within OneNote's engine on newer OS versions like Windows 11, causing complex scripts like Tamil to render incorrectly.
Which fonts are best for typing Tamil in OneNote?
Fonts specifically designed for Indic scripts, such as Nirmala UI, Latha, or Vijaya, are highly recommended. Selecting these fonts ensures that the software can access the correct Unicode glyphs.
How do I report a persistent font rendering bug in OneNote?
You can report rendering issues directly to Microsoft by navigating to Help > Feedback within OneNote. Be sure to provide a screenshot of the jumbled text, state the font you are using, and mention that it appears to be a Unicode glyph-rendering problem.
