Joining Group - Malayalam Nnna

Malayalam Nnna is a joining group that represents the letter ṇa in the Malayalam script, specifically the character ണ. In shaping contexts, it behaves as a non-joining consonant, meaning it does not connect to adjacent letters in a word, either before or after it, in scripts that use cursive connections. This group is used to classify the letter’s behavior in complex text rendering, ensuring that the character appears in its isolated or initial form without ligature formation. It is one of several joining groups defined for South Asian scripts, each tied to distinct consonant classes, and it helps text shaping engines correctly position this letter relative to vowel signs and other conjuncts without unintended joining.
