Single keystroke of colon or slash leads to two of them when editing in Korean

[Youngjoon Kim]

If I type in a, b, c, space, colon, space, I get

abc : 

, which is exactly as I expect.

However, if I were in Korean(한글) mode, I get two colons or slashes by only one keystroke.

For instance, if I type in 가나다, space, colon, space, I get

가나다 ::  

rather than

가나다 : 

My editing experience is totally unpredictable because of that. This is really bothering  expecially when editing a document with both english and korean, such as...

• 사이트 명 : abc
• URL : abc.com
• 관리자 : 김철수

I need to manually delete second colons.

Any help will be appreciated.
