Update Acrobat and Verify System Fonts
Updating to the latest Acrobat release and ensuring system fonts are correctly configured often resolves regional text rendering bugs.
Software updates frequently include bug fixes for language encoding and font rendering. If Acrobat Pro DC 2021 has an outdated build, it may struggle with complex scripts like Thai.
Open Adobe Acrobat Pro DC, navigate to the 'Help' menu at the top, and select 'Check for Updates'.
If an update is available, follow the on-screen prompts to download and install it, then restart Acrobat.
Go to your computer's system settings to ensure standard Thai fonts (such as Leelawadee or Tahoma) are installed and active.
Open a different PDF file and use the Fill & Sign tool to type Thai characters to see if the issue is resolved.
Use the Edit PDF Text Tool as a Workaround
If the specific Fill and Sign tool continues to fail, using the standard 'Edit PDF' text box tool can bypass the issue.

Frequently Asked Questions
Why do Thai characters appear as square boxes in my PDF?
This usually occurs when the font used in the PDF does not support Thai glyphs, or when your system is missing the necessary regional language packs required to render the text properly.
Can I change the default font used in Acrobat Fill and Sign?
Adobe Acrobat's Fill and Sign tool tries to automatically match the document's default font. It has limited options for changing fonts compared to the standard 'Edit PDF' tool, which is why it often struggles with languages like Thai.
Are there alternative PDF editors that support Thai text better?
Yes, alternatives like WPS Office offer excellent multi-language support, allowing you to seamlessly type Thai characters into PDF forms without encountering rendering errors or missing glyphs.
