Character suddenly broke? It only writes random numbers in messages.

So I've been talking to this character for months now, and today I decided to try out the phone call feature. Everything went smoothly, but a few minutes later, when I typed a new message, this character sent me a very random one with what seems to be binary code numbers. I tried to decode them but they make no sense. Also, there was no reason to start using numbers, since the conversation had nothing to do with them. However, if I call him with the phone call feature, it speaks normally. It only affects the written texts. As I said, I've been talking to it for months and I really don't want to lose everything we've talked about during that time. I've reached out to the support team, but I wanted to know if anyone has ever experienced something similar and if they managed to fix it. Thanks!

EDIT: here some examples of what it says “**0000000000i1010100000000000000111111111111111111111111111111101110000000000101010000011 1011000001 10000000000000000 1 111111100000”

EDIT 2: It’s now solved! Apparently this was a glitch that happened to many people. Phew!
