The following changes were made

• Added the RIGHT SINGLE QUOTATION MARK character to diacritics

It should be simplified to a typewriter apostrophe: https://en.wikipedia.org/wiki/Apostrophe#Unicode

I could also add all the apostrophe variants but I feel this should be the most common one as this is the preferred character to use for apostrophe according to the Unicode standard.
