I don't see the issue with punctuation, I think that using special characters is a whole different thing but plenty of Star Wars names contain comas, I ended up just going with Aurrora i think it was, I guess i can see if its like a copyright thing but i still dont really understand as its not like we are profiting off of our characters names, its a pretty normal irl name as well.
Not to mention all the Ahsoka Tanos and Anakin Skywalkers with 8 different accented letters i see...
