Illustrator PDF created with 24.3 sets letter I to overprint
We process PDF files daily and have noticed that files saved as PDF from Illustrator 24.3 will set overprint on for the letter I
There are several different examples if you cannot reproduce.

So you don’t know what settings were used on save? :(

You got the message about changes because I went in the PDF and removed the phone number and email address etc. before uploading to a public site. It is a live label received by the customer as a PDF created by Illustrator 24.3

Interesting. I was finally able to try to 'open' it.
Ai says on importing that the file was modified after being saved... If changes are ignored, it opens inner Ai-layer and no overprint on I-s are present. But if you choose to accept changes and ignore Ai-data anthus directly importing PDF-layer —yellow I-s have overprint indeed!
Can you tell more about the process you use to export a PDF from Ai? What settings, presets? I wonder why Ai believes some external changes were made, when you claim to export these directly... Need more info. Sorry it took me so long to respond though. -

Here is an example PDF File created by Illustrator 24.3 (Mac). The Yellow letter I's get set to overprint on the black background so they do not print.

This is odd...
Are you it's about the overprint though?
Because letters I can be interpreted by Acrobat as ortho lines and it has some special options for dealing with these, making them fatter or thinner in display.
Do they stay invisible when you print?
Can you share the PDF file for others to investigate?
