The slogan has been used to express support for the magazine and the journalists killed in its office by gunmen last week.

The editor and some of France's most celebrated cartoonists were among the 12 people killed.
Three million copies of the next edition, which is being put together by survivors of the attack, will be published. The usual print run is 60,000.
The magazine's lawyer Richard Malka told French radio earlier that it was important to show that staff would "cede nothing" to extremists, the BBC reported.
Following the attack on Wednesday, the gunmen were heard shouting that they had "avenged the Prophet Muhammad".
The magazine was firebombed in 2011 after publishing Muhammad cartoons.
A total of 17 people were killed in three days of terror attacks in Paris last week.

'Right to blaspheme'
The slogan "Je suis Charlie" or "I am Charlie" was widely used following Wednesday's attack on the magazine, as people sought to show their support.
Mr Malka told France Info radio: "We will not give in. The spirit of 'I am Charlie' means the right to blaspheme."
Survivors of the massacre have been working on the magazine from the offices of another French title, Liberation.
Five of Charlie Hebdo's top cartoonists were killed in the attack.
The new edition will be created "only by people from Charlie Hebdo", its financial director, Eric Portheault, told AFP.
Contributions from other cartoonists were declined.
