Text replaced with gibberish after saving

[Paul38685498o8a4]

I recently used Acrobat Pro to enter text in a fillable PDF form I'd received from a financial advisor -- mainly numbers. I then saved it in two places locally (my OneDrive and on a SharePoint) and sent a copy to the advisor. The next day he informed me that almost everything I'd entered was displaying as gibberish. When I checked the copies I'd saved, I saw the same thing. It had looked fine after I'd saved it, but I didn't close and reopen it before sending to verify it was fine.

(I should clarify that I've used Acrobat many times in the past few years to fill out and/or sign forms, contracts, and other documetns, and have never had this happen before.)

Two questions:

1) What caused this, and how can I avoid it happening again?

2) Can I recover the text I originally entered (for example, by downloading a font)? Or is it gone forever?

Hi @Paul38685498o8a4,

Sorry for the delay in responding to your question. Following to check if your issue is resolved or not.

When you tried to add data, were you adding it to the fields, not editing the file? If you were editing the file, it may have happened because the fonts were not embedded. Can't comment on recovery right now as I don't have the full context. 

Is it possible for you to share the files with us?
