Should count quotes to detect if they are part of adjacent words

[wooorm]

This could help the detection of if a quote depicts:

• A possessive apostrophe (Warner Bros.’ movie, three cats’ toys);
• An elision (’sup, ’round, ’nough, ’emselves);
• And actual quote (Then he said “She said, ‘Shut up!’”).

This is actually pretty hard (''no 💩, sherlock', he said', while smiling at 'er cats' toys, is an 'example' of hard to detect quotes).

Especially when the same sign is used for everything in different languages:

• Starting a quote in Bulgarian, Finnish, Norwegian, Swedish;
• the aforementioned reasons (not sure why ending elision is not mentioned in that post);

I think the best way to detect the apostrophes use, is by looking at “enclosed content” (not sure what to call it) to detect pairs of punctuation marks (which other quotes near-never cross).

Closing for now. Would be cool, but hard. Maybe later.
