Is it frowned upon to declare char's this way

Question

char a = "a"[0];

Answer 1

It is bad practice
You can use single quotes to create character
Example char a = 'a';

Answer 2

Why would you ever do that if you can just write char a = 'a';?

Answer 3

I was reading the tutorial about how char's could only be declared using single quotes and I thought I know another way. it was absurd I grant you that
