iOS Mail app encoding headers UTF-8 show bad

Hi,


I’m having issues with some e-mail received in the iOS Mail app.


it happens only with some senders. It happens on multiple up to date iOS 16 iPhone.


the To or CC headers look messed up because of UTF-8 characters. I see stuff like =?UTF-8?




in the Gmail mobile App or Website, there’s no problem


many idea of where the issue is ?


thank you

iPhone 12, iOS 16

What you are seeing are the underlying codes that tell Mail how to decode the text. They do belong there, but you should not see them. Is this mail by chance from a Windows Exchange mail system? To let Apple know about the problem, you can use

Hey again,


I just found this topic where someone had the same issue :

Gmail senders fields are scrambled - Apple Community


His solution was : " it seems that the problem came from a security rule on our Google Admin configuration" ... well I tried to find something in the Google Workspace Admin, but didn't find anything...


I wish I could ask @maxou69 more details, but I don't know how.
