Grapheme Cluster Break - Hangul Syllable Type=LV
Hangul Syllable Type=LV is a specific classification for precomposed Korean syllables that consist of a leading consonant (L) followed by a vowel (V), forming a complete syllable block. In text processing, this value determines how such syllables interact with adjacent characters during grapheme clustering, which is the process of grouping characters into user-perceived units. When an LV syllable appears, it is treated as a single indivisible unit, meaning it does not break apart from following characters unless a boundary is explicitly allowed, such as before a trailing consonant (T) or another L. This ensures that Korean text is segmented correctly for editing, cursor movement, and line breaking, preserving the visual and linguistic integrity of each syllable block without splitting it into its component jamo.
