Could you add two apostrophes to often used special character list: ‘ (U+2018) and ’ (U+2019)? It would be nice if, when clicked, the selected text would be inside these apostrophes. These apostrophes are often used in dictionaries (in many languages) to expain the meaning of a word / phrase.

The special character list can be customized locally by any Interface administrator. At the Polish Wikipedia, you probably want to propose this idea at w:pl:Wikipedia:Kawiarenka/Kwestie techniczne.
But it should be a thing for all Wikipedias. It is used by English dictionaries too.
It is not wanted by all Wikipedias. For example, the English Wikipedia doesn't like "curly" quotation marks: https://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style#Quotation_characters
