This superscript digit often serves a grammatical or phonological function, such as indicating a third-person marker or a particular vowel quality, rather than a standard numeral. Its encoding allows for precise representation in digital text, ensuring that historical or minority language texts retain their unique typographic features without needing complex font substitutions.
