Grapheme Cluster Break - Hangul Syllable Type=T
Hangul Syllable Type=T is a classification for certain precomposed Hangul syllables, specifically those ending in a trailing consonant, known as a final jamo. In text segmentation, this type indicates that the syllable cannot be combined with a following character to form a larger grapheme cluster, because it already includes its final consonant. Instead, it acts as a self-contained unit, typically terminating a cluster. When adjacent to leading vowels or consonants, it does not merge, preventing further extension. This ensures that a syllable like “각” (with a final ㄱ) is treated as a closed sequence, so subsequent jamo start a new cluster. Practically, this affects line breaking, cursor movement, and other text operations, as the syllable is indivisible. It contrasts with open syllable types that allow additional jamo to attach. Thus, Type=T marks a boundary, stabilizing the cluster’s end.
