U+0134 "Ĵ" Latin Capital Letter J with Circumflex Unicode Character
Unicode Version 17.0
Ĵ
U+0134 "Ĵ" Latin Capital Letter J with Circumflex is a modified version of the standard letter J, distinguished by a circumflex accent (^) placed above it. This character is primarily used in the Esperanto alphabet, where it represents the voiced postalveolar affricate sound similar to the English "j" in "judge." It serves as a distinct letter in Esperanto orthography, appearing in words like "ĵurnalo" for newspaper, and its lowercase counterpart is U+0135 "ĵ." The circumflex accent is essential to Esperanto's systematic diacritic-based writing system, which adapts the Latin script to represent unique sounds without introducing entirely new symbols.
