in "" was explicitly marked as url termination character. I don't know why though. Shall I just remove it?
Thanks for pointing out the place! This list seems to contain a lot of punctuation marks and many of them may be a little questionable. For instance are all just variations of parentheses or quotation marks. They are often used as part of an URL rather than to terminate an URL. But since there are so many of them I don't know what is the best way to handle it. Some people may have been relying on this behavior and removing some characters could break it. Maybe you can make it customizable but then that would add to your workload.
I think it's fine to change things and remove "" / "" as force termination characters. Especially if there are things like wikipedia links with them.

Actually, the best change would be to do some logic similar as we do for "(" / ")", where we actually tweak behavior for ")" based on the presence of "(" inside the link or not.
Let's do that if or ever collides with something! Afaik these characters aren't markdown control characters.
Thanks for the quick move. While we are at it, some other characters are in a similar situation. Can you do the same to them too? At least the following two pairs are quite common: “ ” “”
These links should work now too!
