The OuLiPo is a French creative writing comitee created in the 60’s that uses original constraints to foster original works.
One of their most famous works is https://en.m.wikipedia.org/wiki/A_Void (La Disparition in French), which is a 300 page novel entirely written without using the letter E, which is the one banned by the instance. (And yes, there is an English translation that was also written entirely without the letter E)
