Is your feature request related to a problem? Please describe.
In Korea for document editing we use a program called HanCom, its file extension is .hwp (It is similar to MS Word). However, currently this is the only extension I am not able to open with QuickLook

Describe the solution you'd like
It would be great to have support to open these kinds of files with QuickLook!

Describe alternatives you've considered
I have searched many alternatives but with no avail :(
So I was wondering if this feature might be developed in the future!
