U+00F0 "ð" Latin Small Letter Eth Unicode Character

U+00F0 "ð" Latin Small Letter Eth is a letter used in several modern and historical languages, including Icelandic, Faroese, and Old English, where it represents the voiced dental fricative sound heard in the English word "the". In linguistic contexts, it also serves as a phonetic symbol in the International Phonetic Alphabet to denote the same voiced "th" sound, distinguishing it from the voiceless counterpart represented by the letter "þ" (thorn). Its uppercase form is "Ð" (U+00D0), and despite its visual similarity to the digit zero or the letter "d" with a crossbar, it is a distinct alphabetic character with deep roots in medieval Germanic writing systems.
