Dje was constructed by request of
Vuk Stefanović Karadžić. There were several proposed shapes of the letter (one by
Pavle Solarić, another by
Gligorije Geršić). The variant now in use was designed by
Lukijan Mušicki; it was designed by modification of the letter
Ћ, itself a revival of the
old Cyrillic letter
Djerv (Ꙉ). The new letter was adopted in Karadžić's 1818 dictionary and thus entered widespread usage. There was also a Д and Ь ligature variant that has not been added in Unicode as a character, and was used before Dje took its current form. ==Related letters and other similar characters==
