The question marks are being inserted ever since I updated my iPad to the latest IOS version. They replace every apostrophe and quote mark I try to use and trying to edit them out is useless. I really don?t know why I should have to explain these things, Nigel.

Have you tried hitting 'preview' under the reply box, and then editing as necessary within that box?

For some systems it may be necessary to ensure you're using a valid character for the apostrophe (a straight apostrophe rather than an 'inverted comma').
Any reasonably educated person should be able to find what the fault is, and correct it.

To miss-quote Wilde:
To make this error once is unfortunate. to continue doing so seems like carelessness!
