Hangul Syllables

Hangul Syllables is a Unicode block containing precomposed Hangul syllabic blocks for modern Korean. The order of the characters in this Unicode block follows the Hangul alphabetical order of South Korea.

Algorithm for canonical decomposition mappings and character names

The canonical decomposition mappings and the character names of all characters in this Unicode block are algorithmically defined.

The following step gives the index number of the initial consonant, of the vowel, and of the final consonant for a given Hangul syllabic block.

1. Let S = (code point of a character from U+AC00 to U+D7A3, in decimal) − 44032
2. The index number of its initial consonant is S / 588 vowel is (S% 588) / 28 final consonant is S% 28

(x / y is the integer quotient of x divided by y; x% y is the remainder of x / y, also known as the modulo operator)

After getting the index numbers, use the following table to get the canonical decomposition mapping and the character name.

• For the canonical decomposition mapping, simply concatenate the Hangul jamo (element) characters in the "Decomposition" columns below, in the order "initial consonant, vowel, final consonant". The result should match the regular expression [ᄀ-ᄒ][ᅡ-ᅵ][ᆨ-ᇂ]? (one character from U+1100 to U+1112, and then one character from U+1161 to U+1175, and then optionally one character from U+11A8 to U+11C2).
• For the character name, write "HANGUL SYLLABLE " (with the trailing space) first and then concatenate the strings in the "Name" columns below, in the order "initial consonant, vowel, final consonant".

Example

Hangul syllabic block: 쇒 (U+C1D2, decimal 49618)

1. S = 49618 − 44032 = 5586
2. The index number of its initial consonant is 5586 / 588 = 9 vowel is (5586% 588) / 28 = 10 final consonant is 5586% 28 = 14

Therefore, its

• canonical decomposition mapping is ᄉ+ᅫ+ᆵ (U+1109, U+116B, U+11B5)
• character name is "HANGUL SYLLABLE SWAELP"
