Large character sets?

[bbcjared]

So I'm trying to figure out way of using large character sets - Korean. 

There are a lot of characters in Hangul https://memory.loc.gov/diglib/codetables/9.3.html 

When I create custom charset and Trying to use is with 

Code:

hashcat -m 0 -1 Korean.hcchr -a 3 mysuper.hash ?1

I'm getting 

Code:

Custom charset file is too large.

I would love to use -a 3 mode with ?1?1?s etc masks, but obviously having trouble with charset file as it is a bit large (attached)

Thanks
