Question details

When attempting to add a phonetic guide to a term, Microsoft Word displays an EQ field code rather than the properly formatted phonetic characters.

Product: Microsoft Word 365
Device & OS: Windows 11
Scenario: Adding a phonetic guide (ruby text) to words, typically for Asian languages like Japanese.
Observed behavior: The document displays raw EQ field codes instead of the expected phonetic guide above the selected text, even when the required language settings are enabled.

Before you start

Before editing the Windows Registry, make sure you have completely closed all Microsoft Office applications and created a backup of your registry to prevent system instability.

Solution 1Recommended

Rename or Reset the Office Registry Key

Renaming the Microsoft Office registry folder forces Word to rebuild its default settings, which is proven to resolve corrupted field code displays.

This method clears out corrupted user configurations that cause phonetic guides and hyperlinks to display as raw field codes.

Open the Registry Editor

Press Windows Key + R to open the Run dialog, type 'regedit', and press Enter.

Navigate to the Office Key

In the Registry Editor address bar, navigate to HKEY_CURRENT_USER\Software\Microsoft\Office.

Rename the Folder

Right-click on the 'Office' folder in the left pane, select 'Rename', and change the name to 'Officeold'.

Restart Microsoft Word

Close the Registry Editor and open Microsoft Word again. Try adding a phonetic guide to a word to confirm it displays correctly.

Bonus Fix: Resetting this registry key is also known to fix problems with hyperlinks displaying as field codes instead of clickable text.

Solution 2

Disable Word COM Add-ins

Check if a third-party add-in is interfering with how Word renders field codes and phonetic guides.

Solution 3

Create a New Local Windows User Account

If registry tweaks do not work, your current Windows user profile might be corrupted. Testing in a new profile helps isolate the issue.

Frequently Asked Questions

Why is my phonetic guide showing as an EQ field code?

This happens when Word's user settings get corrupted or a system shortcut accidentally toggles field codes on, forcing Word to display the raw EQ field instructions instead of the formatted phonetic characters.

Does adding Japanese as an authoring language fix this issue?

No. While having Japanese installed as an authoring and proofing language is required for the phonetic guide button to be active, it does not fix the bug where an EQ field code is shown instead of the text.

Is it safe to rename the Office registry folder to Officeold?

Yes, renaming the HKEY_CURRENT_USER\Software\Microsoft\Office folder is safe. It simply forces Office to create a fresh registry folder with default settings the next time you open an Office app, acting as a factory reset for user configurations.
