In some posts, I am seeing contractions -- such as that for "I am" -- render in such a way that it reminds me of Turkish words. Sort of saw the same thing happen when typing with letters that have some diacritical marks. This was something I had not seen prior to November 28th. I don't know if it's new to December or not. Saw this on iOS/iPadOS when using Safari. Didn't try the log-in/log-out game to see if that made a difference.
