Unicode Version 17.0

J

U+004A "J" Latin Capital Letter J is a fundamental character in the Latin alphabet, representing the tenth letter in the English alphabet and used across numerous languages including English, French, and Spanish. Originating from the Semitic letter yodh, which shifted through the Greek iota and the Roman I, the distinct form of J as a separate letter with a curved tail emerged in the late Middle Ages, initially functioning as a variant of I before becoming a fully independent consonant. In the Unicode standard, it is part of the Basic Latin block, encoded with the decimal value 74, and serves as the uppercase version of its lowercase counterpart "j" (U+006A). This character is widely utilized in written communication, programming, and digital text, maintaining a consistent typographic shape across most fonts as a simple vertical line with a leftward hook at the bottom.
