Line Break - Hangul LV Syllable
Hangul LV Syllable is a line break class that applies to precomposed Korean syllable blocks of the Hangul syllabary, specifically those with the LV (leading vowel) form, such as 가 or 나. This class dictates that these syllables behave as a single indivisible unit during text wrapping, meaning they cannot be broken apart internally. In practice, a line break is permitted only before or after the entire syllable, never within it, which ensures that the syllable’s constituent jamo characters remain visually and semantically intact. This rule supports the natural reading flow of Korean text, where each syllable block acts as a fundamental orthographic unit, while still allowing flexible line breaking between adjacent syllables to optimize paragraph layout.
