- Product
- PDF Reader/Editor
- Device & OS
- not provided
- Scenario
- Filling out text fields in a PDF form and saving the document for submission or record-keeping.
- Observed behavior
- Upon saving the filled PDF form, the typed alphanumeric text automatically converts into the Wingdings symbol font or otherwise becomes completely unreadable.
Before attempting to fix the issue, identify which application was originally used to create the PDF form and ensure you have a blank, unsaved backup copy of the document.
Check Document Font Embedding Settings
Verify if the original PDF has embedded its fonts properly, as missing or incompatible fonts usually cause text substitution issues.
When a PDF is created, the fonts used in form fields must be embedded or embedded as subsets. If they are missing or improperly embedded, the PDF viewer may not know how to render the text upon saving and will substitute it with a default symbol font like Wingdings.
Open the original, unfilled PDF file in your PDF viewer, click on the 'File' menu, and select 'Properties' or 'Document Properties'.
In the Properties dialog box, click on the 'Fonts' tab to display a list of all the fonts utilized within the document.
Look at the text next to each font name. Ensure it explicitly states 'Embedded' or 'Embedded Subset'. If these labels are missing, the font is not embedded and is likely causing the corruption.
Recreate the PDF Form with Standard Fonts
Fix the issue at the source by using highly compatible standard fonts and enforcing embedding during the PDF export process.
Create and Fill PDF Forms Smoothly with WPS Office
Avoid font corruption and rendering errors by using WPS Office to manage your PDF forms. WPS Office ensures proper font embedding and offers a highly compatible environment for creating, editing, and saving fillable PDFs without data loss.
- 1. Open Your PDF in WPS Office: Launch WPS Office and click on 'PDF Edit' to open your existing fillable PDF form.
- 2. Fill the Form Fields: Click directly into the text fields and type your information. WPS Office will utilize standard rendering to ensure the text remains legible.
- 3. Edit Form Properties (Optional): If you are creating the form, go to the 'Form' tab, right-click the text field, select 'Properties', and assign a standard font like Arial.
- 4. Save the Document Safely: Click 'Menu' in the top left corner, choose 'Save As', and save your document. Your text will be preserved exactly as typed.
Frequently Asked Questions
Why does my PDF text change to weird symbols when I save it?
This happens because the fonts assigned to the fillable form fields were not properly embedded into the PDF when it was created. When the PDF software tries to save the new text, it cannot find the correct font data and defaults to a symbol font like Wingdings.
Can I recover the text from a PDF that has already changed to Wingdings?
Usually, no. Once the file is saved and the text renders as Wingdings, the original alphanumeric data is often permanently corrupted in that specific file. You will need to start over with a blank copy of the form.
Does the software I use to create the PDF matter?
Yes. Different applications have varying default settings for exporting to PDF. Always check your application's export or print settings to guarantee that 'Embed fonts' is actively selected before generating the final PDF form.
What are the best fonts to use in a fillable PDF form?
To ensure maximum compatibility across different devices and PDF readers, it is best to use standard Base-14 fonts such as Helvetica, Times New Roman, Arial, or Courier. These are universally recognized and rarely suffer from embedding errors.
