Line Break - Ideographic

Ideographic is a line break class that designates characters typically used in East Asian scripts, such as Han, Kanji, and Hanja, which are inherently indivisible units of meaning and are not subject to ordinary word spacing. For these characters, line breaking rules allow them to appear at the start or end of a line without requiring a space or hyphen, reflecting their monographic nature. This class also covers punctuation and symbols that align with ideographic conventions, ensuring that text composed primarily of such characters breaks naturally between individual glyphs rather than within them, preserving both visual harmony and semantic clarity in dense CJK text layouts.
