Fix Adobe Acrobat for Android Not Displaying Greek Characters in PDF
Question details
Users are unable to view Greek characters when opening a PDF file in Adobe Acrobat for Android, despite the text rendering correctly in other PDF viewers.
- Product
- Adobe Acrobat for Android
- Device & OS
- Android (Samsung Galaxy tablet)
- Scenario
- Viewing a PDF document containing Greek text on an Android mobile device.
- Observed behavior
- Greek characters are missing or displayed incorrectly in Adobe Acrobat, likely because the required fonts were not embedded when the document was originally created.
Verify if you have access to the original source file (such as the Word document) used to create the PDF, as fixing font display issues usually requires recreating the file with the correct export settings.
Recreate and Export the PDF with Embedded Fonts
The most reliable way to ensure special characters like Greek letters render correctly on all devices is to embed the fonts during the PDF creation process.
When fonts are not embedded, Adobe Acrobat for Android attempts to substitute them with local system fonts. If the device lacks a compatible font for Greek characters, the text will appear broken or missing.
Open the original file (e.g., Microsoft Word, WPS Writer, or InDesign) on your desktop computer.
Navigate to 'File' and select 'Export' or 'Save As', then choose PDF as the file format.
Click on 'Options' or 'Advanced Settings' in the save dialog. Check the box that says 'Embed all fonts' or select the 'ISO 19005-1 compliant (PDF/A)' standard, which forces font embedding.
Save the new PDF document and transfer it to your Samsung Galaxy tablet to view it in Adobe Acrobat.
Use an Alternative Android PDF Reader
If you do not have access to the original source document to embed the fonts, use a different PDF reader that handles missing system fonts better on Android.
View and Edit PDFs Flawlessly with WPS Office
Avoid font rendering errors on mobile devices by using WPS Office. As a powerful all-in-one suite, it perfectly handles PDF viewing, editing, and reliable font embedding across all your smartphones, tablets, and computers.
- 1. Download the App: Download and install WPS Office for free from the Google Play Store or the official WPS website.
- 2. Grant Permissions: Launch WPS Office on your Android tablet and grant the necessary permissions to access your documents.
- 3. Open Your PDF: Tap on the 'PDF' tab or use the built-in file browser to locate and select your PDF file.
- 4. View Seamlessly: Enjoy perfectly rendered text and Greek characters without relying on external desktop tools to fix font issues.
Frequently Asked Questions
Why do Greek characters show up as blank spaces or boxes in my PDF?
This typically occurs when the original author did not embed the required fonts into the PDF file. Without embedded fonts, Acrobat relies on your Android device's default system fonts, which might lack support for specific Greek glyphs.
How can I check if fonts are properly embedded in a PDF document?
You can check this on a desktop computer. Open the PDF in Acrobat Reader or a similar viewer, go to File > Properties, and click on the 'Fonts' tab. It will list all the fonts used in the document and indicate '(Embedded)' or '(Embedded Subset)' if they are properly included.
Does printing a document to PDF automatically embed all fonts?
Most modern 'Print to PDF' virtual drivers embed fonts by default, but it is not guaranteed for every system. To ensure maximum compatibility, it is best to use the native 'Export to PDF' or 'Save As PDF' feature in your word processor and manually verify the embedding options.
Can I embed missing fonts into a PDF directly from my Android tablet?
No, font embedding generally needs to be done during the document creation process on a desktop application like Word, WPS Writer, or InDesign. Android PDF viewers do not currently have the capability to retroactively embed local desktop fonts into an existing PDF.
