There are a few different ways of doing this.

First, we can add "Hangul Jamo" to 2.1.4. IgnorableBlocks (D).

Secondly, we can use the Hangul_Syllable_Type as defined in  
HangulSyllableType.txt.

That would block (in Unicode 5.1) 1100..11FF.

What I have not found any Unicode definition of, so it has to be  
exceptions. are for the Bangjeom, 302A..302F. Help would be appreciated.

Please advice, specifically those who know how additional characters  
are added to 5.2.
