Can’t type the letter I️ , showing up weird. A little box or the letter A and a question mark inside of a box.

Me too. It started on Friday night. I did the update and it didn’t do anything to help. It’s so frustrating!!

I’m having the same issues!

Thank you! Worked. I sure hope Apple puts out a permanent solution soon.

I did this. It only works in messaging. My emails have symbols and even what I am typing NOW has symbols. I use my phone for work and this is embarrassing! I HAVE DONE ALL SUGGESTIONS.

It started a day or two ago. Upgraded to the new IOS because i thought it would fix the problem, but it did not.

Yes I just updated and this is happening.

No, it happened to me on before iOS 11.1 and even with the update the problem is still there

I'm still on iOS 10 and it's Doing this

Do this. It works and you’ll still have pedictive text.

I tried this fix and it says you need 2 characters in the replacement field. How are you supposed to get around that?

That worked, thank you so much!

Phrase will not allow a single character. I tried adding ““I”” and this is what happens.

Mine started pre-update and continued afterward. Though oddly after the update sometimes it looks okay to me but my recipient sees the A + ? on the other end.

I’m having this problem as well on both my iPhone 6S and I Pad Pro. Very annoying.
