My friend saved some text into Gmail notes IMAP folder via iPhone.
However, now when looking at them via the online gmail.com interface, they appear to be gibberish.
Example (altered for privacy):
It looks like an encryption/encoding of a sort, but doesn't seem to match anything I'm familiar with. It's clearly neither base64 or base32, or even base85.
As far as I know, no encryption was on on the iPhone's end. This hasn't happened to all messages, only seemed to start in the last few days. Is this just corruption or what?
