The French satirical paper whose Paris offices were attacked in 2015 is reprinting the caricatures of Islam's Prophet Muhammad that the gunmen who opened fire on its editorial staff cited as their motivation.
The move was announced on Tuesday, a day before 13 men and a woman accused of providing the attackers with weapons and logistics go on trial on charges of terrorism on Wednesday.
In an editorial this week accompanying the caricatures, the paper said the drawings "belong to history, and history cannot be rewritten nor erased".
The January 2015 attacks against Charlie Hebdo and, two days later, a kosher supermarket, touched off a wave of killings claimed by the ISIL (ISIS) armed group across Europe.
Seventeen people died in the attacks - 12 of them at the editorial offices - along with all three attackers.
The attackers, brothers Cherif and Said Kouachi, claimed their attack on the newspaper in the name of al-Qaeda. As they left the scene at Charlie Hebdo, they killed a wounded policeman and drove away.
Two days later, a prison acquaintance of theirs stormed a kosher supermarket on the eve of the Jewish Sabbath, claiming allegiance to ISIL. Four hostages were killed during the attack.
The Kouachi brothers had by then holed up in a printing office with another hostage. All three attackers died in near-simultaneous police raids.
The supermarket attacker, Amedy Coulibaly, also killed a young policewoman.
