Accept diagonal quote marks (’)

[tussosedan]

Please add support for these to treat them as regular quote marks. They're the default in Google Docs, and having to keep converting stuff pasted from the internet is a pain. Example: R’ U’ R U’ F U’ R’ U’ R U F’

[Roman-]

More generally, the program should interpret (or replace) all of these characters as (with) a single quote: ʼ᾿ߴ՚’`

I think only apostrophe U+0027, prime U+2032, and right single quotation mark U+2019 should be accepted. Prime is technically the correct one. In particular I do not like grave accent being used.
