How to Troubleshoot Thai Font Display Problems in OneNote for Android
Question details
The user needs to investigate and resolve issues where Thai text and fonts are not displaying correctly on Android tablets and smartphones.

- Product
- Microsoft OneNote
- Device & OS
- Android
- Scenario
- Typing, pasting, or reading Thai language text within the OneNote application on an Android device.
- Observed behavior
- Thai characters and fonts render incorrectly or appear corrupted in OneNote, despite functioning properly in other Office applications on the same device.
Before troubleshooting, ensure that your Android operating system and the Microsoft OneNote application are updated to the latest versions available in the Google Play Store.
Diagnose and Isolate the Font Display Issue
Determine if the Thai font problem is system-wide or isolated entirely to the OneNote application.
Since font rendering issues can stem from either the Android system or the app itself, isolating the problem is the most crucial first step. If the font works elsewhere, the issue requires an app-specific fix from Microsoft.
Open Microsoft Word, Excel, or PowerPoint on your Android device.
Type or paste the exact same Thai text that is displaying incorrectly in OneNote into the alternative application.
Check if the Thai fonts render correctly in these apps. Also, test the text in a non-Microsoft third-party application on your phone.
Take a screenshot or photo of the corrupted text in OneNote to keep as a reference when submitting a bug report to Microsoft Support.

Report the Bug and Seek App Updates
If the issue is confirmed to be isolated to OneNote, you will need to rely on official app updates or support channels.
Try WPS Office for Reliable Font Rendering on Android
If OneNote and other Microsoft apps are struggling with Thai font displays, WPS Office offers an excellent, lightweight alternative for managing your documents and notes on Android. It provides robust multi-language support and perfect compatibility with Microsoft Office formats.
- 1. Install WPS Office: Download and install WPS Office directly from the Google Play Store on your Android device.
- 2. Create a new document: Open the app and tap the '+' icon to create a new text document to serve as your notes.
- 3. Type in Thai: Switch to your device's Thai keyboard and type naturally; WPS Office will accurately render the complex fonts.

Frequently Asked Questions
Why do Thai fonts display correctly in Word but not in OneNote on Android?
This typically indicates a specific rendering bug within the OneNote application's internal engine, rather than a system-wide font issue on your Android device. Different Office apps sometimes use different rendering engines.
Can I install custom Thai fonts directly into OneNote for Android?
No, OneNote for Android does not support installing custom third-party fonts directly into the app. It relies on the default fonts provided by the Android system.
Will clearing the app cache fix the font display issue in OneNote?
Clearing the app cache may resolve temporary visual glitches. You can try this by navigating to your Android Settings > Apps > OneNote > Storage and tapping 'Clear Cache', then restarting the app.
