- Product
- Adobe Acrobat Reader
- Device & OS
- Android
- Scenario
- Viewing a PDF containing Turkish text using Reading Mode while the device language is set to US English.
- Observed behavior
- Specific Turkish characters such as ı, i, ğ, and ş fail to display in the app's Reading Mode.
Ensure you have a stable internet connection to check for software updates, and temporarily toggle off Reading Mode to verify if the missing characters display correctly in the standard PDF layout.
Update Adobe Acrobat Reader and Android System
Installing the latest versions ensures that bugs related to font rendering and language support in Reading Mode are patched by the developer.
Software updates often include critical bug fixes for regional language support and font extraction. Ensuring both your app and operating system are up to date is the primary step in resolving this display error.
Go to the Google Play Store on your Android device and search for Adobe Acrobat Reader to check for pending updates.
Tap the Update button if available. Once the installation finishes, reopen the PDF to see if the Turkish characters are visible in Reading Mode.
Navigate to your device Settings, select System, and tap System Update. Download and install any available Android OS updates.

Add Turkish to Device Language Settings
Changing or adding local language settings on your device can help the application correctly identify and render region-specific characters.
Switch to Original PDF Layout
If Reading Mode continues to drop characters due to parsing limitations, switching back to the standard view will preserve the document's original embedded fonts.
Use WPS Office for Flawless Multilingual PDF Viewing
WPS Office provides a robust mobile PDF reader with a highly compatible Mobile View feature. It correctly renders embedded fonts and international characters, including Turkish, ensuring a smooth and accurate reading experience without dropping critical text.
- 1. Download WPS Office: Get WPS Office for free from the Google Play Store on your Android device.
- 2. Open your PDF: Launch WPS Office, tap on Files, and select the PDF document containing the Turkish characters.
- 3. Enable Mobile View: Tap the Mobile View icon at the bottom of the screen to optimize the text layout for your smartphone while preserving character integrity.

Frequently Asked Questions
Why do some Turkish characters disappear only in Reading Mode?
Reading Mode (or Liquid Mode) extracts text and reflows it to fit smaller screens. If the application's extraction engine fails to map specific embedded fonts or regional characters (like Turkish ı, ş, ğ) correctly, they may be dropped or replaced by blank spaces in the reflowed view.
Will changing my Android system language change all my apps to Turkish?
If you set Turkish as the primary language, your system UI and most apps will change to Turkish. However, simply adding Turkish as a secondary language in your Android settings often allows apps to download necessary language and font packs without altering your main UI language.
How can I report this missing character bug to Adobe?
You can report the issue by navigating to the Help & Support section within the Adobe Acrobat Reader app settings. Be sure to include your device model, Android version, app version, and if possible, a sample PDF that replicates the issue.
