The Korean language uses Hangul (phonetic) characters and Hanja (Chinese) characters. A Hangul character is a single syllable created by combining an initial consonant, a medial vowel, and sometimes a final consonant; sorting is based on these elements in the order they occur.
The sort order of Hangul consonants is as follows:
The sort order of Hangul vowels is as follows:
The sort order of Hanja characters is determined by pronunciation. To specify the sorting of Hanja characters, add Hangul characters enclosed in brackets after the Hanja characters in the index marker text, as in the following example:
Group titles for index entries are defined in the GroupTitlesIX paragraph on the IX reference page. In Korean documents, the default group titles are as follows:
A new index keyword, <$hangul>, is automatically added to the SortOrderIX paragraph on the IX reference page when the index is created. You can specify your own sort order for Hangul characters by replacing <$hangul> with actual characters in the order you want them to sort.
