Superscript Latin Small Letter I

The Superscript Latin Small Letter I at U+2071 is a small raised form of the letter i in the Superscripts and Subscripts block, used when an i must appear at superscript height as an actual character rather than as formatting. It is most often encountered in phonetic, linguistic, or technical text that needs plain-text superscript letters to survive in filenames, database fields, search indexes, or environments with limited rich-text support. In linguistics and pronunciation notes, superscript letters can mark secondary articulation, reduced sounds, or annotation-like detail, and this character may appear beside other superscript Latin letters in narrow phonetic transcriptions. In scholarly editing, dictionaries, and language-learning materials, it can also be used for compact inline notes where a raised i is part of the transcription convention rather than a mathematical exponent. Its use in ordinary mathematics is limited: variables and powers are normally written with text styling or markup, not with this precomposed superscript letter. A practical caution is that it can be confused with a styled lowercase i, but plain-text search and normalization may treat it differently, so it is best used only when the superscript form is semantically intended.
