How to Fix Missing Turkish Characters in Embedded PowerPoint Fonts
Question details
The user needs to resolve an issue where specific Turkish characters are replaced or go missing when a presentation with embedded fonts is opened on another computer.

- Product
- PowerPoint
- Device & OS
- not provided
- Scenario
- Viewing or editing a shared presentation containing Turkish text on a different device.
- Observed behavior
- Turkish characters such as ç, ş, ı, ü, and ö are replaced by substitute fonts or display incorrectly because the embedded font failed to include them.
Verify that your chosen presentation font natively supports Turkish Unicode characters by typing them in a new text box and ensuring the font name does not automatically change.
Clear and Re-embed the Entire Font
PowerPoint may only embed characters used at the exact moment the font was first embedded. Resetting the embedding process forces it to capture recently added Turkish characters.
When 'Embed only the characters used in the presentation' is selected, PowerPoint often fails to update the embedded font cache if new special characters are added later. Selecting 'Embed all characters' prevents this issue.
Go to File > Options > Save. Scroll down to the 'Preserve fidelity when sharing this presentation' section and uncheck 'Embed fonts in the file'. Click OK.
Save your presentation to apply the changes, and completely close the PowerPoint file.
Reopen the presentation. Go back to File > Options > Save. Check 'Embed fonts in the file' and select the option 'Embed all characters (best for editing by other people)'.
Click OK and save the file again. All Turkish characters are now fully embedded and will display correctly on other computers.

Check for Unintended Font Substitutions
Ensure that the 'Insert Symbol' feature didn't secretly apply a different, unsupported font to your Turkish characters.

Frequently Asked Questions
Why does 'Embed only the characters used' cause missing letters?
If you add new special characters to your presentation after initially saving with this setting, PowerPoint often fails to update the internal embedded font cache. As a result, the newly added characters are left out of the file.
How do I know if a custom font supports Turkish characters?
Type the required Turkish characters (ç, ş, ı, ü, ö) into a text box and apply your custom font. If the characters display as blank squares, question marks, or if the font name automatically changes in the ribbon, the font does not support them.
What are the best fonts for extensive Unicode and multiple language support?
System fonts such as Arial Unicode MS, Calibri, Tahoma, and Times New Roman feature comprehensive Unicode support, making them highly reliable choices when typing in Turkish or using special symbols.
