The Wikipedia has the following information about this codepoint:
Yodh (also spelled jodh, yod, or jod) is the tenth letter of the Semitic abjads, including Phoenician yōd 𐤉, Hebrew yud י, Aramaic yod 𐡉, Syriac yōḏ ܝ, and Arabic yāʾ ي. Its sound value is /j/ in all languages for which it is used; in many languages, it also serves as a long vowel, representing /iː/.
The Phoenician letter gave rise to the Greek Iota (Ι), Latin I and J, Cyrillic І, Coptic iauda (Ⲓ) and Gothic eis .
The term yod is often used to refer to the speech sound [j], a palatal approximant, even in discussions of languages not written in Semitic abjads, as in phonological phenomena such as English "yod-dropping".
