Frequently Asked Questions
Why do Thai characters look jumbled in Adobe Acrobat on my iPhone?
Adobe Acrobat Reader for iOS currently lacks native support for complex script editing like Thai. This causes characters to render incorrectly, overlap, or display as boxes when you try to type or edit text.
Can I still view Thai PDFs correctly on my iPhone?
Yes. While editing Thai text causes display errors, simply opening, viewing, and reading a pre-existing PDF with Thai text works perfectly fine in the Acrobat app.
Are there other languages affected by this iOS PDF editing limitation?
Yes. Other complex script languages that rely on specific character positioning and ligatures, such as Arabic, Hindi, or Hebrew, may experience similar editing limitations on mobile apps without dedicated support.
