I am trying to conform to the British practice (specifically Oxford Style Guide) and I am a little confused which to use to mark a nickname:
Andrew 'Andy' Johnson
Andrew "Andy" Johnson
I know following the rules I should use single inverted commas, however the first one looks a tad weird to me. I have seen the latter option a lot on newspapers and business cards but not the former.
I am going to use that for email signatures and names on business cards.
