D with comma below.

This letter was first introduced by Petru Maior in his 1819 book Ortographia romana sive Latino-Valachica, una cum clavis, qua penetralia originationis vocum reserantur...: "d sicut Latinorum z ac cyrillicum ?"^[2].

In 1844 Ioan Eliade introduced d again in his magazine Curierul de ambe sexe as a substitute for ?^[3].

On 23 October 1858 the Eforia Instruc?iunii Publice of Wallachia issued a decree in which, among other rules, d was for the third time adopted instead of Cyrillic ?. However, this rule will not be fully adopted until later^[4].

Taking the matter in his hands, internal affairs minister Ion Ghica stated on 8 February 1860 that whoever in his order ignored the new transitional alphabet rules, was going to be fired^[5].

In Moldavia, the transitional alphabet and the letter d was adopted much later. In his grammar published in Paris in 1865, Vasile Alecsandri adopted this sign instead of ?, viewing the coma below d as a small s (d was oftenly pronounced , . This was also the case with ?ss and ?ts)^[6].

This letter was abandoned in 1904 and is no longer in use. In Unicode it is represented by the letter D followed by a combining comma below (U+0326). It closely resembles the Livonian letter (d with cedilla, U+1E10 and U+1E11).
