Mick BurrellWe probably don't think too much about the apostrophe we use when typing and it probably doesn't bother us but I recently had an issue. On a forum, I've set up a user name (using my Mac) that includes one. All was well till I tried to log in using my phone. I couldn't! After double checking my name and password I came to the conclusion that it must be the apostrophe. The phone can offer you several versions if you hold your finger on the key but none of those worked either. I then discovered in Settings>General>Keyboards that Smart Punctuation was turned on. Turning it off gave me the same apostrophe as the Mac which allowed me to log in - it didn't look any different to the others I'd tried but clearly has its own character code.
