- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Inserting and viewing special symbols and text formats within a OneNote notebook.
- Observed behavior
- OneNote generally supports Unicode characters, but certain character sets, fonts, or input methods can cause the characters to display incorrectly as blank boxes or fail to insert.
Verify that your computer's operating system language settings and keyboard layout correctly match the specific character sets you are trying to type.
Use Compatible Fonts and Built-in Insertion Methods
Ensure you are using a font that supports the required Unicode glyphs and use standard Office insertion methods to prevent missing characters.
While OneNote supports Unicode natively, individual fonts do not contain every single Unicode character. If a character appears as a square box, it is typically a font limitation rather than a OneNote limitation.
Highlight the text displaying incorrectly. Go to the 'Home' tab and change the font to one known for extensive character support, such as 'Arial Unicode MS', 'Segoe UI Symbol', or 'Lucida Sans Unicode'.
Navigate to the 'Insert' tab on the OneNote ribbon, click on 'Symbol', and select 'More Symbols'. Choose the specific Unicode character from the dialog box and click 'Insert'.
Type the hexadecimal code for the Unicode character (for example, type 20AC for the Euro symbol) and immediately press 'Alt + X' on your keyboard to convert the code into the corresponding symbol.

Utilize the Windows Character Map
Use the built-in Windows Character Map utility to find and copy complex Unicode characters when direct keyboard entry fails in OneNote.
Experience Flawless Character Formatting with WPS Office
If you frequently encounter formatting limitations or character display issues in Microsoft applications, consider switching to WPS Office. It provides comprehensive support for complex Unicode characters, ensuring your documents, notes, and symbols display perfectly across all your devices without the hassle of missing glyphs.

Frequently Asked Questions
Why do my Unicode characters appear as blank square boxes in OneNote?
This happens when the font currently applied to your text does not contain the specific glyphs for the inserted Unicode characters. Highlighting the boxes and changing the font to 'Segoe UI' or 'Arial Unicode MS' usually resolves the display issue.
Can I use standard Alt codes to type symbols in OneNote?
Yes, you can use traditional Alt codes by holding down the 'Alt' key and typing the specific decimal code on your numeric keypad. However, standard Alt codes are limited to specific regional character sets and do not cover the entire Unicode spectrum.
Does OneNote for Mac support the same Unicode characters as the Windows version?
Yes, OneNote for Mac fully supports Unicode characters. However, instead of using the Windows 'Alt + X' trick, you should use the macOS built-in 'Character Viewer' by pressing 'Control + Command + Space' to find and insert your desired symbols.
