It is my understanding that the first one has the Korean Hangul
syllables in the old location and the second one in the new location.
If you don't have any pre-Unicode 2.0 Hangul syllables, you should be
using the second one. If you do have pre-Unicode 2.0 Hangul syllables,
you should migrate them to their Unicode 2.0 locations and then start
using the second one.
If you have no plans to store Hangul syllables, you would probably be
OK with the first one for a while, but this might be problematic, as
it probably doesn't support any of the other characters added since
Unicode 1.1.
