Has anyone experienced Chinese subject titles when receiving emails from Binance?

Hello,

I have been attempting to change my email on account for security.

I have a completely fresh proton email set up, which I am brand new to.

When sending the verification code through, it comes through as English but the subject is Chinese. Has anyone else had this? I've sent it three times and it's the same, so it's definitely ME. BUT I do not trust it.

What am I meant to do? It's so confusing. I'm so paranoid.
