Was the form generated in Hebrew? More specifically, was the PDF form created with a Hebrew-language version of Adobe Acrobat? Please realize that generating form fields in Acrobat may not be the same thing as receiving a PDF written in Hebrew and then using a version of Acrobat that portrays text from left to right like, say, Roman or Cyrillic languages.
Text is to a large degree determined by the author. Similarly, text fields are to a large degree determined by the person who generates the form. If the form field was generated to display text from right, it won’t much matter if you fill out the form in Hebrew and expect it to flow from right to left. And even in Acrobat Pro, you won’t be able to change that without deleting the existing form fields (if possible) and recreating the form fields to portray type from right to left.
If the form was generated in Hebrew, with a Hebrew-language version of Adobe Acrobat, this may be a more complex problem. If not, the problem is relatively simple to identify but not easy to fix. Please don’t ask me how I know …
@funny_Wish6bc5 Does the text appear reversed while you're typing, or does it look correct while typing and become reversed only after you leave the field or save the PDF?
