The issue occurs when you type the letter “i” on the standard iOS keyboard. Instead of seeing an “i” you’ll see the keyboard autocorrect to the letter “A” with a symbol.

Apple’s temporary solution is as follows:

Go to Settings > General > Keyboard > Text Replacement.
Tap “+”.
For Phrase, type an upper-case “I”. For Shortcut, type a lower-case “i.”

Apple released iOS 11.1 on Oct. 31. The update brings new emoji to the platform, including Woman with Headscarf, Bearded Person, Breastfeeding, Zombie, Person in Lotus Position, Sandwich, Coconut, and many others.
