Question

Problem with Thai text disappearing in Fill & Sign function

Hi,

I’m facing an issue with Acrobat Reader and left a review on the App Store. The developer suggested I escalate the issue here in the community.

I am experiencing a bug in Acrobat Reader on both my iPhone and iPad (though I mainly use the app on my iPad).

When using the Fill & Sign feature, any text I enter completely disappears if it contains Thai characters. This happens whether I type Thai text alone, combine Thai with English, or combine Thai with numbers. On the other hand, it works perfectly fine when typing in English only.

I have attached two screen recordings to demonstrate:

1 Video 1: Showing the Fill & Sign function, where the Thai text consistently disappears.

2 Video 2: Showing a different text insertion tool where the Thai text does not disappear.

I am currently using this second method as a temporary workaround, but frankly, it is much less convenient than using Fill & Sign.

 

Device Details:

iPad: iPad Pro (11-inch) (3rd generation) running iPadOS 26.5

iPhone: iPhone 16 Pro running iOS 26.5

 

Hope this bug can be resolved!

 

Thanks in advance.

Due

    Hi there 

     

    Our team is unable to reproduce this issue in-house. Could you confirm if you are using a fillable PDF form or the fill and sign tool?

    Hi Amal,

     

    I have tested this with both fillable and non-fillable PDF.

    The Thai text issue only occurs with the non-fillable PDF (or PDF forms where Acrobat cannot auto-detect the fillable fields).

     

    Please find the attached screen recordings for reference.

     

    Thanks,

    Due

      Hi Amal,

       

      Thanks for your reply.

      The version of Acrobat I’m using is the same in both iPhone and iPad:

      Version 26.04.61 (20260529.081653)
