How to Fix Incorrect Khmer Unicode Characters in Word and Excel
Question details
Users are experiencing issues where Khmer Unicode characters display or type incorrectly in Microsoft Word and Excel.

- Product
- Microsoft Word and Excel
- Device & OS
- Windows
- Scenario
- Typing or reading documents and spreadsheets containing Khmer language text.
- Observed behavior
- Khmer Unicode characters render improperly or show up as incorrect symbols, typically due to Windows keyboard layout incompatibilities rather than an application failure.
Ensure you have administrator privileges on your computer, as you will need to install new keyboard layouts and apply system updates.
Install and Select a Compatible Khmer Unicode Keyboard
Installing a dedicated Unicode keyboard layout like NiDA 2.0 ensures Windows passes the correct character data to your Office applications.
Incorrect character input is most frequently a Windows-level language issue rather than a bug within Microsoft Office itself. Relying on default system keyboards might not fully support complex scripts.
Search for and download a trusted Khmer Unicode keyboard layout, such as the Khmer Unicode Keyboard NiDA 2.0, from an official or reputable repository.
Extract the downloaded files, run the installer executable, and follow the on-screen prompts to add the keyboard layout to your Windows system.
Navigate to Windows Settings > Time & Language > Language & region. Click 'Add a language', search for Khmer, and install it.
Click the language abbreviation (e.g., ENG) on your taskbar or press the Windows key + Spacebar to switch your active input method to the newly installed Khmer keyboard before typing in Word or Excel.

Install Pending Windows and Office Updates
Updating your system can introduce better built-in support for language inputs and fix known Unicode rendering bugs.
Try WPS Office for Excellent Multi-Language Support
If you are struggling with complex script rendering or unresolved language-input bugs in Microsoft Office, consider switching to WPS Office. It is a highly compatible, free alternative that handles Unicode characters smoothly.
- 1. Download the installer: Visit the official WPS Office website and click the free download button.
- 2. Install the software: Run the installer and follow the quick setup wizard.
- 3. Open your files: Launch WPS Writer or WPS Spreadsheet and open your existing documents to view your Khmer text accurately.

Frequently Asked Questions
Why does my Khmer text look like unreadable squares or boxes?
This happens when your system lacks a font capable of displaying Khmer characters. Ensure you have standard Khmer Unicode fonts like 'Khmer OS' or 'DaunPenh' installed and applied to your text.
Will reinstalling Word or Excel fix my typing issues?
No, reinstalling Office applications usually does not fix language-input problems. These issues stem from the Windows operating system's keyboard layouts or missing system fonts.
How do I quickly switch back to English from the Khmer keyboard?
You can rapidly toggle between all installed keyboard languages by holding down the Windows key and pressing the Spacebar.
