Acrobat Pro DC for mac doesn't show uniks-ucs2-h encoding properly

Hi, I'm recently using Acroabt Pro DC for mac and I found something weird.

Acrobat Pro DC for windows show pdf files with font encoded in Uniks-UCS2-H properly. Uniks-UCS2-H encoding is well known encoding method for creating pdf files written in Korean. 

However, Acrobat Pro DC for Mac doesn't show pdf files well. 

I understand that the chrome browser doesn't support Uniks-UCS2-H encoding method because it is an web browser, not a pdf program. But I think Acrobat Pro DC for Mac need to supoort this.
