U+1D4B "ᵋ" Modifier Letter Small Open E Unicode Character

U+1D4B "ᵋ" Modifier Letter Small Open E is a typographic symbol classified as a spacing modifier letter, specifically a superscript or raised form of the open-mid front unrounded vowel sometimes represented by the IPA symbol ɛ. It is used primarily in phonetic transcription and linguistics to indicate a modified or secondary articulation of the vowel sound, often appearing in the context of the International Phonetic Alphabet or its extensions to denote a shorter, fainter, or otherwise altered pronunciation. This character is distinct from the lowercase epsilon or other similar letters and is encoded in the Unicode standard to support precise textual representation in digital environments without reliance on font-specific styling.
