Fix Alt Codes Displaying as Question Marks in OneNote for Windows 10
Question details
Users experience an issue where typing Alt codes in OneNote for Windows 10 results in boxed question marks, despite the same codes working perfectly in other applications.
- Product
- Microsoft OneNote for Windows 10
- Device & OS
- Windows 10
- Scenario
- Inserting special characters or symbols using keyboard Alt codes.
- Observed behavior
- The intended special characters fail to render and instead appear as boxed question mark symbols.
Verify that your keyboard's Num Lock is turned on, as Alt codes require the dedicated numeric keypad to register correctly.
Use the Unicode Input Method
Since OneNote for Windows 10 processes legacy Alt codes differently, using the Unicode method ensures the correct character is always rendered.
Many Alt codes listed in standard online references are not fully supported by the UWP framework used in OneNote for Windows 10. The Unicode hexadecimal method acts as a reliable workaround for inserting special characters.
Look up the 4-character hex Unicode value for the specific symbol you want to insert (e.g., 00A9 for the copyright symbol).
Type the Unicode value directly onto your OneNote page where you want the symbol to appear.
Immediately press 'Alt + X' on your keyboard. This will convert the alphanumeric code into the corresponding special character.
Upgrade to the Standard OneNote Desktop Application
Switching to the main OneNote desktop application resolves compatibility issues with traditional Alt codes.
Switch to WPS Office for Reliable Document Editing
If you are frustrated with discontinued applications and inconsistent formatting across different Microsoft Office versions, consider switching to WPS Office. It provides a lightweight, highly compatible, and free alternative with consistent behavior for keyboard shortcuts and special character inputs.
- 1. Download WPS Office: Visit the official WPS website to download the free installation package for your operating system.
- 2. Install the Suite: Run the installer and follow the on-screen instructions to set up WPS Office.
- 3. Edit Seamlessly: Open your documents in WPS Writer, Spreadsheet, or Presentation and enjoy consistent formatting and editing features.
Frequently Asked Questions
Why do Alt codes work in Word but not in OneNote for Windows 10?
OneNote for Windows 10 was built using the Universal Windows Platform (UWP), which processes text input differently than traditional desktop applications like Microsoft Word. This difference in frameworks leads to inconsistent support for legacy Alt codes.
What is the difference between OneNote and OneNote for Windows 10?
OneNote is the standard desktop application included with Microsoft 365, while OneNote for Windows 10 was a standalone app pre-installed on older Windows 10 devices. The desktop version offers broader feature support and is the version Microsoft will continue to update.
Can I still use OneNote for Windows 10?
Yes, you can continue using it for now, but Microsoft has announced that it will reach its end of support in 2025. It is recommended to transition to the standard OneNote desktop app before then to avoid losing access to support and updates.
