-// Hangul is a syllable based script. Unicode reserves a large range
-// for precomposed hangul, where syllables are already precomposed to
-// their final glyph shape. In addition, a so called jamo range is
-// defined, that can be used to express old Hangul. Modern hangul
-// syllables can also be expressed as jamo, and should be composed
-// into syllables. The operation is rather simple and mathematical.
-
-// Every hangul jamo is classified as being either a Leading consonant
-// (L), and intermediat Vowel (V) or a trailing consonant (T). Modern
-// hangul syllables (the ones in the precomposed area can be of type
-// LV or LVT.
-//
-// Syllable breaks do _not_ occur between:
-//
-// L              L, V or precomposed
-// V, LV          V, T
-// LVT, T         T
-//
-// A standard syllable is of the form L+V+T*. The above rules allow
-// nonstandard syllables L*V*T*. To transform them into standard
-// syllables fill characters L_f and V_f can be inserted.
