Unfortunally, I have been looked any of a episode and I don't think Wèi is not suppose to look like that. Ok, just looked at the names bellow:
"Wèi" - This one is a corrected ways because of a "è" words coming out.
"Wei" - ..And this one is incorrect.. That's why it should be a "è" names at the middle side (like Pokèmon do, it's because the name of a word was at the middle side.) it can be a Chinese and Japanese to make a name of..
I hopefully understand you guys..
