Solution 1Recommended

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.

1
Download a compatible keyboard layout

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.

2
Install the keyboard layout

Extract the downloaded files, run the installer executable, and follow the on-screen prompts to add the keyboard layout to your Windows system.

3
Add Khmer to Windows languages

Navigate to Windows Settings > Time & Language > Language & region. Click 'Add a language', search for Khmer, and install it.

4
Switch keyboard inputs

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.

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.
