*
* The Original Code is CharToByteX11Johab.java
*
* The Initial Developer of the Original Code is Deogtae Kim
* <dtkim@calab.kaist.ac.kr> (98/05/03) and
* Based on: Hanterm source code adapted by Jungshik Shin
* <jshin@pantheon.yale.edu>
*
* Contributor(s):
* Deogtae Kim <dtkim@calab.kaist.ac.kr> (99/08/28)
* Jungshik Shin <jshin@pantheon.yale.edu>
*
* - Purposes:
* 1. Enable displaying all 11,172 Modern hangul syllables with Hanterm
* johab fonts on Unix
* 2. Enable displaying some of Unicode 2.0 ancient hangul syllables
* with Hanterm johab fonts on Unix
* 3. Enable displaying all of Unicode 2.0 ancient hangul syllables with
* possible future extended Hanterm johab fonts on Unix
*
* - Installation Instructions:
* 1. Install Hanterm Johab fonts and a proper font property file to Unix system.
* (Confer http://calab.kaist.ac.kr/~dtkim/java/)
* 2. Make a directory "jdk1.x.x/classes/"
* 3. Compile this class into "jdk1.x.x/classes/"
*
* - Hangule syllable break rule algorithm descriptions:
* The algorithm used here is slightly different from that of the Unicode standard 2.0.
* The standard saids that a (canonical) hangul syllable block is a sequence of leading
* consonants and a sequence of vowels and an optional sequence of trailing
* consonants.
* I think this unncessarily complicate matters.
* So, the algorithm chosen here is:
* A (non-canonical) hangul syllable block is the longest sequence comprised of
* an optional leading consonant and an optional vowel and an optional trailing consonant.
* The skipped leading consonants and vowels are considered as fillers.
* The merit of this algorithm is that any sequence of jamos can be composed validly.
