When I plot a graph in R all the characters get transformed in strange characters

I use a session connected to RStudio Server.

I tried to restart my session, to use another session (another profile without any packages), to restart RStudio Server and to restart the server. I also tried to reinstall R. I still get the same problem.

How can I solve this problem ?
