im not sure if you can type in the characters or use them in the dropdown, but no, as i said. i just wasnt sure how to support them.
when i was first starting this plugin i asked for anyone to please explain to me how to even type them to screen with a regular keyboard as a start, but i had no friends at the time and no one answered me. i also asked google, but i guess everyone who needs to alreadyy knows how, or i wasnt asking the right questions, cuz i couldnt find anything relevant to my searches
as far as adding it in the future
its possible, but it would be much further in the future if at all
if anyone can tell me if you can type the nonstandard characters into constructs textboxes, itd be a start
