There is some sort of typing assist feature on my Apple products that substitutes a correction that is itself incorrect and it's been around for a decade or more and I've been living with it for all this time, but it's really annoying. Whenever I type a contraction such as wasn;t it corrects it it with wasn't;t. I'm guessing that somewhere along the line I had a keyboard that had the ; where the ' was and I end up more often than not typing the semicolon in error.
I have tried to locate the problem in the spelling dictionary and the typing assist feature of text substitution, but there is no such correction there. Does anyone have any suggestions on how to correct this? I have even see the behavior in the iPhone/iPad simulator when using the computer keyboard to enter text, but not every time. I have several computers and iOS devices at home and at work and it happens on all of them. The problem doesn't;t seem to be app specific since it happens in nearly every app.

to see if it's in there - I suspect it isn't, but it's an easy test
