- Product
- Adobe Acrobat / PDF Forms
- Device & OS
- not provided
- Scenario
- Filling out interactive text fields within a PDF form using non-Latin (Chinese) text.
- Observed behavior
- Latin characters appear correctly, but Chinese characters are invisible or show up as blank spaces in the text field.
Make sure your operating system has Unicode or Asian fonts installed (such as SimSun, Microsoft YaHei, or Arial Unicode MS) before attempting to change the form's font settings.
Change Form Field Font to a Unicode-Supported Font
Update the properties of the affected text fields to use a font that natively supports Chinese characters.
By default, PDF form fields are often set to standard Western fonts like Helvetica or Times Roman. These fonts do not contain the necessary glyphs for Chinese characters, causing the text to appear blank. Changing the field to a Unicode font resolves this visibility issue.
Open your PDF document in Adobe Acrobat. Go to 'Tools' and select 'Prepare Form' to enable form editing capabilities.
Right-click the problematic text field where characters are missing and select 'Properties' from the context menu.
In the Text Field Properties window, click on the 'Appearance' tab to access font settings.
Click the 'Font' dropdown menu and select a font that supports Chinese characters, such as Arial Unicode MS, SimSun, or Microsoft YaHei. Close the properties window and save the document.
Embed the Font into the PDF Document
Ensure the selected font is embedded within the PDF so that the characters display correctly for any recipient, regardless of their installed fonts.

Frequently Asked Questions
Why do only Latin letters show up while Chinese characters disappear in my PDF form?
This happens when the form field is assigned a standard Western font like Helvetica or Times New Roman. These fonts do not contain the necessary character outlines (glyphs) to display Chinese, causing the text to render as invisible or blank spaces.
Do the recipients of my PDF form need to have the Chinese font installed?
If the specific Chinese font used in the form field is not embedded in the PDF document, recipients will need that exact font installed on their devices to view the text correctly. Embedding the font ensures universal visibility.
What are the best default fonts for filling out Chinese PDF forms?
Fonts like Microsoft YaHei, SimSun, and Arial Unicode MS are highly recommended because they contain comprehensive character sets for Chinese and ensure excellent readability across different platforms.
Can I edit the PDF form on my mobile device?
Yes, but you will need a PDF application that supports form filling and has access to necessary device fonts. Using the WPS Office mobile app allows you to fill out PDF forms with multi-language support seamlessly.
