How to Fix Greek Letters Missing from a Font in PDF Forms
Question details
The user needs to display Greek characters correctly while typing with a specific dotted font inside an interactive PDF form.

- Product
- Adobe Acrobat / PDF Editor
- Device & OS
- not provided
- Scenario
- Filling out an interactive PDF form using a customized or dotted font that includes Greek letters.
- Observed behavior
- Greek letters fail to appear in the PDF form, despite the exact same font working properly in other text editors like WordPad.
Ensure you are using the latest version of your PDF editor and verify that the specific font file is fully installed on your operating system.
Verify Font Embedding and Supported Glyphs
Check the PDF document properties to see if the font is properly embedded and supports the required Greek characters.
A font might work in external applications because the operating system dynamically substitutes missing characters. However, PDF forms require strict embedding. If the font lacks embedded Greek glyphs or is not fully supported by the PDF form fields, the characters will remain invisible.
Launch your PDF file in Acrobat or your preferred PDF editor, then navigate to 'File' and select 'Properties'.
In the Document Properties window, click on the 'Fonts' tab to view a list of all fonts used in the document.
Locate your specific dotted font in the list. Check its font type (e.g., TrueType) and see if it is marked as '(Embedded)' or '(Embedded Subset)'.
If the font is not embedded or lacks Greek support, use the form editing tools to change the field's font to a standard system font (like Arial or Times New Roman) that fully supports Greek letters.

Frequently Asked Questions
Why do some fonts work in WordPad but not in my PDF form?
WordPad and similar word processors rely on your operating system to substitute missing characters dynamically. PDF forms, on the other hand, require the exact glyphs to be embedded within the document's assigned font to display them correctly.
How can I embed a font into a PDF document?
Fonts are typically embedded when you originally export or save a document as a PDF from a word processor. During the save process, look for an 'Options' or 'Advanced' menu and ensure the 'Embed fonts in the file' checkbox is selected.
What should I do if my chosen font lacks Greek letters?
If the specific dotted font you selected does not natively contain the Greek alphabet glyphs, you will need to edit the PDF form properties and switch to a different font that fully supports Greek characters.
