It’s not just the English language that iOS developers seem to have problems with, it’s also one of the many Indian texts.
After dealing with auto-correct issues in prior editions of iOS 11, Apple has pushed out iOS 11.2.6 to fix a major bug that caused iPhones that received a certain character to crash. Worse yet, this bug could lock users out of third-party messaging apps like WhatsApp and (i)Messages as well. This is the main issue addressed in the changelog.
We should expect a more cohesive bandage to all of these little annoying, yet critical bugs with a new approach to software development as of iOS 12.
