Vim special character input(₩,¥,€ )

When we want to input currency characters, such as dollor=$.
There is no symbol such as Korean unit ₩.

1. Input(i)
2. <ctrl>+k , then ? mark will be on screen.
3. When we want to input Korean currency Won(₩).
4. Type upper case W and =, then ₩ will be on.
5 In case of Japanese currency unit symbol, type upper case Y and -, then ¥ will be on screen. Chinese symbol is same but pronunced differently(Yen-Japanese, Yuan-Chinese)
6.Euro sign would be <ctrl>+k+=+e  €


 :digraph command will show a lot.
