You keep posting nearly the same question over and over, and I really have no idea what you wish to accomplish.
Stop being all hung up on a couple bloody characters. It's Anglocentric as fuck. Use the proper braille table for displaying them and actually learn the braille of the language you're learning, or if you don't want to do that, just install
$1, add the characters you want to its dictionary and they'll show up as whatever you want them to look like.
One of the subjects I had at uni this year was English Phonetics. Now that uses a bunch of characters that don't display right, and in many cases don't even read right. Well, I used the list of symbols on the IPA website to see how each symbol should be pronounced and add it to the symbols dictionary, and then used the IPA Braille article on Wikipedia to see what dots each symbol should have and add that too. Then I set up WinCompose as well to have easy access to all these symbols, because they just aren't available on the keyboard by default, and copy-pasting them is not an option when the tests have such a short time limit.
Was it a pain? Sure. But I set it up and now it works. So if you want to be able to read and write these characters so much, stop posting questions on Reddit and get to work.
