iCloud data and Reminders icon in Chinese

What pertinent facts have you not told us about this iPhone’s past - country where purchased, places where used, previous ownership, whether purchased directly from Apple or an Authorized Apple Retailer, etc.?

• What model iPhone?
• What model number (Settings > General > About > Model Number)?
• What iOS version (Settings > General > About > iOS Version)?
• Purchased in what country?
• Used in what country?

I have an iphone 13 (purchased from Apple) and just noticed the exact same characters next to my Reminders. Very creepy weird!! Maybe it is a common issue, but I’d like Apple to explain why these characters are showing up here. It’s the same on my iPad (also purchased from Apple).

I took a screen shot of the characters and put them in Google translate. You know what it says? Reminders!!! Hah. So it is the Chinese word for Reminders but still doesn’t belong on our phones………
