U+1E9F "ẟ" Latin Small Letter Delta Unicode Character

U+1E9F "ẟ" Latin Small Letter Delta is a typographic variant of the Greek letter delta, adopted into the Latin alphabet for specialized linguistic use. It represents a voiced dental fricative sound, similar to the English "th" in words like "that," and is employed primarily in medieval and early modern Latin texts for transcribing Greek loanwords or in phonetic notation. This character is distinct from the standard Greek delta (δ) and is part of the Latin Extended-D block, added to Unicode to support historical and scholarly transcription needs.
