Typing ' after a link (external or internal) should insert a single apostrophe.
Actual result
Typing ' after a link instead inserts '' (when Auto pair brackets is on).

Not what you want, but the workaround I use is to type an apostrophe from the keyboard rather than letting the OS and Obsidian manipulate the outcome of pressing the straight-quote keys.
On a Mac, the following all work without automatic pairing:
OPT ] for left (opening) single quotation mark
SHIFT OPT ] for right (closing) single quotation mark or apostrophe
OPT [ for left (opening) double quotation mark
SHIFT OPT [ for right (closing) double quotation mark
There is a downside to using such “fancy” (typographically correct) apostrophes: if some Obsidian notes use the more common “programming” single quotes, searching text with apostrophes becomes cumbersome (as we don’t know which kind of apostrophe we should look for). It’s thus better to be consistent, and it’s easier to be consistent by using the usual single quotes.
Hopefully it’s not too hard to not double ' right after a link, for the Obsidian wizards.
Would also be useful if Obsidian was apostrophe (diacritics in general) agnostic when searching, or at least had a toggle to be either agnostic or restrictive in the results it returns.
